Hello, Folks. Welcome to my blog on RVM Commands.
Please read my blog https://sufinhacks.wordpress.com/2017/04/19/ruby-installation-using-rvm/ for Ruby Installation instructions.
Following are some commonly used rvm commands:
Install a Ruby Version
rvm install version-number
Eg: rvm install 2.3.3
Use a Ruby Version
You may have multiple versions of ruby installed using rvm. You may need to switch between ruby versions when working on multiple projects
rvm use version-number
Eg: rvm use 2.3.3
Create a gemset
It is a good practice to use different gemsets for different projects. Gemsets are nothing but independent containers that you can use to keep gems separate from each other.
rvm gemset create gemset_name
Eg: rvm gemset create my_gemset
The above command will create a gemset named my_gemset for the current ruby version. That is if you are using ruby 2.3.3 as the current ruby version, then my_gemset will be created for the ruby version 2.3.3
Delete a Ruby Gemset
rvm gemset delete gemset_name
Eg: rvm gemset delete my_gemset
Delete a Ruby Version
rvm remove version-number
Eg: rvm remove 2.3.3
