# RVM clean house
# Do not be surprised if one day you'll see something like this:
# $ du -hs ~/.rvm
# 1.2G    /home/vagrant/.rvm
# To solve the problem run rvm cleanup all. It will remove stale source folders / archives and other miscellaneous data associated with rvm.
rvm cleanup all

# To cleanup outdated gems run rvm gemset empty [gemset]. It will remove all the gems, so you will need to run bundle install after that.
rvm gemset list
rvm gemset empty default

# Run rvm gemset globalcache enable. It will enable global gem cachedir, which will be used to store gems (we do not want to store the same gem for each Ruby version, obviously)
rvm gemset globalcache enable
