Step 5. Setup Default Ruby Version

First of all, check currently installed ruby versions on your system. So that we can which version is using currently by the system and which is set to default.

# rvm list  rvm rubies   * ruby-2.3.0 [ x86_64 ]    ruby-2.3.3 [ x86_64 ] => ruby-2.4.0 [ x86_64 ]  # => - current # =* - current && default #  * - default 

After that use rvm command to setup default ruby version to be used by applications.

# rvm use 2.4.0 --default  Using /usr/local/rvm/gems/ruby-2.4.0 

Step 6. Check Current Ruby Version.

Using following command you can check the current ruby version is used.

# ruby --version  ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
