  1. Easy way to create gemset per project using RVM (Example)

Assuming that you are already on your project directory. Now run these commands from your CLI.

  • Step 1: rvm gemset create [name of gemset]
  • Step 2: rvm --rvmrc [ruby version here]@[name of gemset]
  • # Note: You can check your current ruby version by running "ruby -v" from your console.
  • Step 3: Refresh your directory.
  • # You can simply do this by checking out of your directory and going back to that directory again.
  • Step 4: RVM will ask you a simple Yes, No, View, Cancel question. Press Y for yes.
  • Step 5: You're done! Run bundle install.

Live example:

Current directory: Projects/DumbProject | Current ruby version: ruby-1.9.3-p327

  • $ rvm gemset create dumb
    gemset created dumb => /Users/awesomeness/.rvm/gems/ruby-1.9.3-p327@dumb
  • $ rvm --rvmrc ruby-1.9.3-p327@dumb
  • $ cd..
  • $ cd DumbProject
  • Do you wish to trust '/Users/awesomeness/Projects/DumbProject/.rvmrc'?
  • Choose v[iew] below to view the contents
  • y[es], n[o], v[iew], c[ancel]> y
  • $ y
  • $ bundle install

Note: rvm gemset empty - will only delete gemsets from current project while in that directory

Note: In this case, i always put .rvmrc file in my global .gitignore file so I don't need to bother every project I fork with pull requests. You can look at this reference on how to set up your global gitignore: <>

*Cleaning Up*

### remove all old versions of the gem gem cleanup rjb

### choose which ones you want to remove gem uninstall rjb

### remove version 1.1.9 only gem uninstall rjb --version 1.1.9

### remove all versions less than 1.3.4 gem uninstall rjb --version '<1.3.4'
