Installation Ruby on Rails
Learn the basics of installing Ruby on Rails with an example.
Installing Ruby on Rails
Ruby on Rails is a powerful web development framework written in the Ruby programming language. It is used to create web applications quickly and easily, and is popular among developers for its ease of use and scalability. Installing Ruby on Rails is simple and straightforward, and can be done in just a few steps.
Step 1: Install Ruby
The first step in installing Ruby on Rails is to install the Ruby programming language. This can be done on Windows, MacOS, or Linux, and the best way to install it will depend on your operating system. On Windows, it is recommended to use the RubyInstaller, which can be found here. Once you have downloaded and installed RubyInstaller, you can run the following command to verify that Ruby is correctly installed:
ruby -v
If the correct version of Ruby is installed, you should see something like the following output:
ruby 2.3.1p112 (2016-04-26) [x86_64-darwin15]
Step 2: Install Rails
Once you have installed Ruby, the next step is to install Rails. This can be done by running the following command:
gem install rails
This command will download and install the latest version of Rails. Once the installation is complete, you can verify that Rails is correctly installed by running the following command:
rails -v
If the correct version of Rails is installed, you should see something like the following output:
Rails 5.0.0
Step 3: Create a New Rails App
Once you have installed Ruby and Rails, the next step is to create a new Rails app. This can be done by running the following command:
rails new my_app
This will create a new Rails app called “my_app” in the current directory. You can then cd into the my_app directory and run the following command to start the Rails server:
rails server
Once the server is running, you can open a browser and navigate to http://localhost:3000/ to see the default Rails welcome page. Congratulations, you have successfully installed Ruby on Rails!
