You might need to set GEM HOME for the cleanup to work  You can check what paths exist for gemfiles by running   gem env   Take note of the GEM PATHS section   In my case  for example  with gems installed in my user home   export GEM HOME     gem ruby 2 4 0  gem cleanup

gem cleanup uses system commands  Installed gems are just directories in the filesystem  If you want to batch delete  use rm -R    gem environment and note the value of GEM PATHS cd  lt your-gem-paths gt  gems ls -1  grep rjb-  xargs rm -R
