How to install Ruby on your machine
First, before installing Ruby, you must install Ruby Version Manager (RVM). The simplest way to do this is to enter the following in the console:
\curl -L https://get.rvm.io | bash -s stable
Once this command has run, you must restart your terminal.
Once you have installed RVM as above, you can now install the most recent version of Ruby. To do this, you must enter the command:
rvm install ruby-2.4.2
Note: you must enter the most recent Ruby version, you can check the latest version <a href="https://www.ruby-lang.org/en/downloads/">here</a>.
You may be asked to enter your password to complete the installation.
The final step is to ensure the RubyGems version is up to date. To do this type:
gem update --system
Now you have successfully installed and updated to the most recent version of Ruby!
Note: If you try install a old ruby version maybe you can get a ssl error. You can solve it with rvm install ruby-x.x.x --disable-binaries
