According to the project’s own website, RVM (Ruby version manager), RVM is a command-line tool that allows you to easily install, manage, and work with multiple ruby environments from interpreters to sets of gems. In short, with this tool, you can easily install different versions of Ruby on any system.

By using RVM, you have the main advantage of being able to install the latest stable version of the language. As mentioned earlier, we can install different versions of Ruby.

Install Ruby on Ubuntu 20.04 / Debian 10

So the first thing we have to do is open a terminal and install some necessary packages before starting the installation.

:~$ sudo apt install gnupg curl

As you can see, these packages include curl which will be in charge of downloading RVM.

To do this, run this command which will download RVM and then run it.

:~$ curl -sSL https://get.rvm.io | bash

Then make RVM available as a command by refreshing the user profile.

:~$ source /home/angelo/.rvm/scripts/rvm

To prove that everything went well, just show the version of RVM installed.

:~$ rvm -v
rvm 1.29.10-next (master) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

Now we can show you all the versions of Ruby available for installation.

:~$ rvm list known

As you can see, there are several. However, at the time of writing this post, the last available stable version is 2.7.1 so we’ll install it:

:~$ rvm install ruby-2.7.1

RVM can handle several versions of Ruby on one system. So we need to set which one will be the major version.

:~$ rvm --default use ruby-2.7.1

Then, display the version of Ruby with the following command:

:~$ ruby -v

In this case, Ruby is already installed and ready to start work.

If you ever want to uninstall it, just run the following command:

:~$ rvm remove ruby-2.7.1

This completes the whole process. So, enjoy it.

Conclusion

Ruby is a pretty powerful language. It seems to be given little credit, but it is still widely used and large server applications, as well as scripts, are developed with this language.

Downloading RubyInstaller

As mentioned in the title, we’ll be using RubyInstaller to install Ruby on Windows 10. In the first place, go to the RubyInstaller page. In the download section, please choose the version corresponding to your computer’s architecture. At the time of writing this post, the most recent version is 2.6.5.-1.

Once the installer is downloaded, simply run it to start the installation.

The following box shows various configuration options. It’s a good idea to check all of them since this adds Ruby to the PATH, as well as associates the .rb and .rbw files with the Ruby installation. It is also possible to choose UTF-8 as the external encoding parameter.

However, some gems or packages require compiling in C, so select the option to install MSYS2.

Once all the preparations have been made, the wizard will start the installation.

Wait a few seconds while the assistant does his job. Finally, select the option to run the ridk install. This will install the MSYS2 and the development toolchain.

A new window will be displayed immediately to continue the installation. Please leave everything by default to execute a full installation. Press enter to start the process.

After a few minutes, the word success will appear in the window. This means that the installation was completed. Please close the window.

Runs the interactive mode in Ruby

To check the performance of the Ruby interpreter, simply open a CMD and run the following command:

irb

To exit, simply type the following command:

exit

Ultimately we have seen how to install Ruby on Windows 10. From now on you can use this powerful programming language. Before I say goodbye, I invite you to check out our post about Django on Windows 10.

Prerequisites

On the program page, it is indicated that it is necessary to have installed Visual C++ Redistribuable for Visual Studio 2015 x86 or x64. In theory, it would only be enough to have this version installed for the server to flow correctly. However, owners of 64-bit computers require both versions of the package. Now, after trying to run the server, the system dropped an error with the msvcr110.dll library. Well, the solution to this problem is to install all versions of Visual C++ published to date today. To simplify this task I give you a link to download all packages compressed into a single file. Just scroll down and select All VC Redistributable Packages (x86_x64) (32 & 64bits).

After decompressing, install all packages one by one.

Downloading EasyPHP Devserver

This is a package that combines the Apache 2.4.25 server, the MySQL 5.7.17 database, and the PHP 7.1.3 programming language. It also includes phpMyAdmin and Xdebug. The first thing we have to do is to go to the official website of the program and download the latest version:

Once you have downloaded the file, double-click on it to start the installation. Select the installation language

Then select the installation directory of the program:

The wizard then offers to create a desktop shortcut.

After the previous settings have been made, the program will begin to install.

The wizard will start the installation process.

After a few minutes, the program will complete the installation. It then executes the program.

Configuring the server

Once the installation is complete, please place the program icon in the taskbar. Right-click on it and select the Open Dashboard option to configure it.

Immediately a new tab will open in the browser with the initial settings of the program.

As you can see, there are two buttons relating to the http server and the database server. By default, they are stopped. So to start them, just click on both start buttons. After doing this, you will see both servers running, the modules being used and the listening ports.

Testing the server

When you click on the sprocket under HTTP server, you enter the server configuration. Once there, click on Server URL and you will be redirected to the server address.

From the server configuration, you can also see that the path to save our web pages is as follows: C:\Program Files (x86)\EasyPHP-Devserver-17\eds-www\. To check that everything is working correctly, please edit the file phpinfo.php with your preferred text editor.

Once the file is open, please enter the following code:

<html>
<body>
	<h1>Osradar </h1>
	<p>Welcome to Osradar</p>
	</body>
	</html>

Then reload the server URL and you will see the next result:

By right-clicking on the program icon, you will see some interesting options. Such as to stop and restart the servers, check the ports or simply exit the program.

This program can be used in a portable way. Additionally, each time you want to use it, just click on the program icon. Also, to uninstall it, you just delete the installation folders.

Conclusion

Finally, we have seen how to simply set up a web server with EasyPHP DevServer. This tool supports several programming languages like PHP, Python, Ruby, Perl. Also, running MySQL as a database manager. So it is a very useful tool for personal development environments. This is all for now before I go I invite you to check our post on Node.js in Windows 10

Ruby on Rails makes Ruby more popular

The truth is that Ruby is still widely used today, but when compared to Python, PHP or Java is far behind. So it is no wonder it is not so easy to learn.

However, thanks to the efficiency of Ruby on Rails, many people have turned their eyes back to this language. Ruby on Rails is a fairly robust framework for creating web applications.

Some of the highlights of Ruby on Rails are as follows:

• It uses many configuration conventions. This makes the framework, once installed, ready to work.
• In Rails, there are several ways to do a certain thing. That is, it makes collaboration easier and the code easier to understand.
• With Ruby on Rails, you’ll have a framework that uses the DRY (Don’t Repeat Yourself) principle. With this, duplicity is eliminated and it makes it very agile.
• Open Source, so licensing should not be a problem for you.

If we add a robust and stable operating system like Debian to Ruby on Rails, then we have a great combination. So, let us start.

Install Ruby on Rails on Debian 10

Now we can start installing Ruby on Rails on Debian 10. The best way to do this is manually to get the latest stable version available. This way we will be able to take better advantage of its features.

First, start a new terminal session and run the following commands:

:~$ sudo apt install build-essential curl nodejs

Also install the following packages:

:~$ sudo apt install gawk autoconf automake bison libffi-dev libgdbm-dev libncurses5-dev libsqlite3-dev libtool libyaml-dev pkg-config sqlite3 zlib1g-dev libgmp-dev libreadline-dev libssl-dev

In case you do not have sudo enabled, I recommend you read our post about it.

How to enable sudo on Debian 10 Buster?

Now, you need to download the GPG key to install RVM (Ruby Version Manager) and then install Ruby.

:~$ curl -sSL https://rvm.io/mpapis.asc | sudo gpg --import -
:~$ curl -sSL https://rvm.io/pkuczynski.asc | sudo gpg --import -

Then, download the RVM script.

:~$ curl -sSL https://get.rvm.io | sudo bash -s stable --ruby

After that, refresh the bash profile.

:~$ source /etc/profile.d/rvm.sh

Now, check the version installed.

:~$ ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux]

Now it is your turn to install Ruby on Rails. At the time of writing this post, the latest stable version is 5.2.3. So to install it, just use this command as root:

:~$ su
:~# gem install rails -v 5.2.3

Now, we can start a new project.

Start a new Ruby on Rails project on Debian 10

Now we’re going to create a new project for Ruby on Rails. To do this, create a folder with the name of the project and access it. Of course, choose the path and the name.

:~# exit
:~$ mkdir /home/angelo/example
:~$ cd /home/angelo/example

So, create the project.

:~# rails new example

Note: If you can not use rails command. Just log out and log in again.

Now it is necessary to serve the project. For that it is enough to use this command:

:~# cd example
:~# rails s

Note: you can run bundle install command to install all gem missed. After that, run rails s command again.

Also, you can specify an IP address and port.

:~# rails server --binding [Ip_address] --port [Port]

Finally, open your web browser and go to http://SERVER-IP:3000 and you will see this.

So, that is it.

Conclusion

Thanks to Ruby on Rails you can create great web applications for the market. All this, thanks to the potential of Ruby as a language and the structure of this framework. Using it with Debian 10 as a system is a guarantee of success.

Ruby is an extremely powerful programming language for the web platform that enables developers to create blazingly fast web services without any problem. It’s being maintained and released as an open-source, free project. There are numerous frameworks, package managers and others out there that make things even more interesting.

If you’re interested in the web, then learning Ruby can be your go-to. Let’s get started by setting up the latest RubyMine from JetBrains on your Linux system right now!

Setting up Ruby

Before installing RubyMine, you have to install the Ruby programming language package on your system. Of course, what you’re going to do if your system don’t have the language package?

Run the following command according to your Linux distro –

• Ubuntu

sudo apt update && sudo apt upgrade -y

sudo apt install ruby-full

• Debian

sudo apt-get update && sudo apt-get upgrade -y

sudo apt-get install ruby-full

• Fedora

sudo yum install ruby

• Arch Linux

sudo pacman -Syyuu

sudo pacman -S ruby

• Other Linux distros

THere are also other ways of installing Ruby programming language support on your system. You can build Ruby from source, or install RVM (Ruby Version Manager). Let’s check out both ways.

• Installing Ruby from source

Download the latest tarball of Ruby.

Then, extract the downloaded TAR.GZ.

tar -xf ruby-2.6.0.tar.gz

Now, time to build and install the Ruby language.

./configure

Note – you can also add “–prefix=<custom_dir>” flag for specifying the installation location of the Ruby language.

make

sudo make install

• Installing using RVM

At first, install the GPG key for RVM –

gpg2 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

Now, install RVM –

\curl -sSL https://get.rvm.io | bash -s stable

Or, you can install the default Ruby and Rails with the following command –

\curl -sSL https://get.rvm.io | bash -s stable --rails

• Installing RubyMine from Snap store

The easiest way of installing RubyMine is through the snap. Snap is available on all the major Linux distros and there’s a pretty high chance that your system supports snap as well.

At first, make sure that you have “snad” set in your system. Then, run the following command –

sudo snap install rubymine --classic

Using RubyMine

Fire up RubyMine –

Let’s start by completing the installation process. Select not to import settings.

Now, select the UI theme of RubyMine.

Choose the keymap scheme you’re comfortable with.

Select the default plugins.

Install “Featured plugins” you need.

Let’s “Evaluate for free” RubyMine.

Enjoy!

The post Install JetBrains RubyMine on Linux appeared first on Linux Windows and android Tutorials.

JetBrains brings us in RubyMine perhaps the best IDE to develop in Ruby. RubyMine has a pretty good design, elegant, sober and functional to start the work.

It has quite modern features such as the possibility to auto-complete the code and the partial search for code, to increase the speed of coding. Of course, it has debugging and code testing tools, as well as support for HTML, CSS, LESS Coffee script, which also makes it ideal for Ruby on Rails.

Let’s install this fantastic IDE for Ruby

First of all, what you have to do is install Ruby. I think it’s obvious, however, I remind you to do it. It’s possible to do it without so many problems with the following command.

:~$ sudo apt install ruby-full

Installation on Ubuntu 18.04 and Linux Mint 19 is simple because it is available as a snap package. In other words, the whole installation is reduced to one command.

:~$ sudo snap install rubymine --classic

Next, launch it.

The first use of RubyMine

When you first run the application. We will be asked to import some previous configurations. Some of them may come from a previous version. Next, the installer will ask us if we accept the license agreement.

Now you will begin to customize this IDE for Ruby. First, select the UI.

Now, you have to set the keymap scheme.

Now the next step is to integrate the plugins. Leave it that way by default.

Now it’s the turn of the community plugins. You can also install it.

RubyMine is not free so you will be asked to activate the license. However, you can request a trial for 30 days.

Then, the application will ask you if you want to send data anonymously, for statistics and possible improvements.

Finally, you can use RubyMine.

Now it is time to create a New project.

Obviously, it is convenient to create a project with something related to Ruby, but note that it is possible to start Bootstrap or Foundation projects. I created one of Bootstrap, but create one of whatever you want.

Now, start to code!! 😀

Conclusion

The development of applications needs tools that facilitate the process. One of those tools is IDE’s that help to make coding fast and efficient.

The post RubyMine is a fantastic IDE for Ruby appeared first on Linux Windows and android Tutorials.

Ruby on Rails is a web application development framework that uses Ruby as its programming language. In addition, it is open source and applications are created from the MVC architecture (Model, View, Controller). In short, not only is it free to use, but you can also help make it better.

So, in this post, you will learn to install Ruby on Rails on Debian 9.

Two ways to install it

A great advantage of Ruby on Rails is that it can be installed in two possible ways on Debian 9. As you know Debian 9 is a very safe operating system and for many developers, it is the main option to build their applications.

One of the options is to do it from the APT package manager. It’s quite simple and puts Ruby on Rails at a distance command.

The other option is to do it through RVM (ruby version manager), this way is more complex but we can have access to specific versions.

1. Using APT

Actually, this way of installing Ruby on Rails on Debian 9 is quite simple to do. It all boils down to the execution of the following command.

:~$ su
:~# apt install ruby rails

And that’s it.

This form of installation, has a big problem, you will not have a new version of the framework. Depending on many factors this can be either a problem or a big problem. It’s simple, but I don’t recommend it.

2. Install Ruby on Rails using the RVM

In contrast, this method is a little more complicated but believe me it’s better. In the first place, it is necessary to install some dependencies.

:~# apt install build-essential curl nodejs

Next, add the RVM GPG keys.

:~# curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg2 --import -

Then, use curl to download the RVM installation script. With this script, you will install Ruby.

:~# curl -sSL https://get.rvm.io | bash -s stable --ruby

3.- Installing RVMThen, make RVM available for the user.

:~# source /etc/profile.d/rvm.sh

Now, install ruby. So it’ll take a while.

:~# rvm install ruby

After that, check the Ruby version.

:~# ruby -v

Now, install Rails.

:~# gem install rails -v 5.2.1

Using this command we tell gem to install a specific version of Rails. In this case, I chose the latest stable version at the time of writing this post.

3. Start a new project

Now you can start a new project. To do this create the folder where the site will be located. It is important that these commands are not executed by the root user, to avoid permission problems.

:~$ mkdir /home/angelo/example
:~$ cd /home/angelo/example

Of course, replace the name and the Path of your project.

Now, create the project. Replace example for your project name.

:~$ rails new example

Note: If you can not use rails command. Just log out and log in again.

Then, run the following command to start creating the project as such.

:~$ rails s

Note: you can run bundle install command to install all gem missed. After that, run rails s command again.

Finally, open your web browser and go to http://IP_SERVER:3000. You will see something like this.

And that’s all.

Conclusion

Ruby on Rails is a widely used framework worldwide. Many of the world’s most famous companies use this framework to design their web applications. Therefore, it is a good idea to learn something about it. Today you learned how to install it on Debian 9.

Please share this post with your friends

The post How to Ruby on Rails on Debian 9? appeared first on Linux Windows and android Tutorials.

Rails is a framework for web applications that runs on the Ruby programming language. This means that you will not use PHP in this framework, so you must first learn the ruby language before using this popular framework.

Following the paradigm of the Model View Controller (MVC) pattern Ruby on Rails tries to combine simplicity with the possibility of developing real-world applications by writing less code than with other frameworks and with a minimum of configuration.

Let’s get to work!

1.- Upgrading the system

To install Ruby on Rails on Ubuntu 18.04 we will use RVM (ruby version manager) which will help us to install it more easily. First we will open a terminal emulator and proceed to update the system. Doing so is highly recommended to maintain optimal operating system performance. As root user, write:

:~$ sudo -i
:~# apt update && apt upgrade

After the process of updating the operating system is finished, we must install node and curl, two tools necessary to continue with the tutorial.

:~# apt install nodejs curl

Next, import the signature key to verify the download we will do with RVM.

:~# curl -sSL https://rvm.io/mpapis.asc | gpg --import -

Next we have to install RVM and the stable version of Ruby

:~#  curl -sSL https://get.rvm.io | bash -s stable --ruby

We proceed to update the shell to be able to use RVM:

:~# source /usr/local/rvm/scripts/rvm

And then we’ll install rails.

:~# gem install rails

Optionally we can choose a specific version of Rails, the syntax would be:

:~# gem install rails -v x.x

replace x.x with the version of your choice. I repeat, this is optional.

now, We verify the installation done:

:~# ruby -v
:~# rails -v

now to verify the installation, we must create a new project.

:~# cd /home/angelo/
:~# rails new example

We enter the project folder:

:~# cd example

And finally we must start the rails WEBrick server:

:~# rails s -b 0.0.0.0

And finally we go to the web browser and access the project created with our ip address through port 3000.

http:IP:3000/

And that’s all there is to it! The main advantage of installing Ruby on Rails with this method is that we can use specific versions of the framework.
