When I go with gem list from my app folder, the terminal displays the list of all gems installed on my local machine. I want instead to see the project related gems.

To check if a specific version is installed, just add --version , e.g.: gem list -i compass --version 0.12.
To find out what the most recent Rails version is, use the command gem search rails | grep "^rails " .
The Gem command is included with Ruby 1.9+ now, and is a standard addition to Ruby pre-1.9. Because local_gems relies on group_by , it returns a hash of the gems, where the key is the gem's name, and the value is an array of the gem specifications.
Step 1: Check Ruby Version 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.
