Follow the steps given below for installing Ruby on Rails.
First, check if you already have Ruby installed. Open the command prompt and type ruby -v. If Ruby responds, and if it shows a version number at or above 2.2.2, then type gem --version. If you don't get an error, skip Install Ruby step. Otherwise, we'll install a fresh Ruby.
If Ruby is not installed, then download an installation package from rubyinstaller.org. Follow the download link, and run the resulting installer. This is an exe file rubyinstaller-2.2.2.x.exe and will be installed in a single click. It's a very small package, and you'll get RubyGems as well along with this package. Please check the Release Notes for more detail.
Install Rails − With Rubygems loaded, you can install all of Rails and its dependencies using the following command through the command line −
C:\> gem install rails
Note − The above command may take some time to install all dependencies. Make sure you are connected to the internet while installing gems dependencies.
Use the following command to check the rails version.
C:\> rails -v
Output
Rails 4.2.4
