bundle command gives permission denied - /var/lib/gems How to overcome?

Question

From trying to do bundle I get:

$ gem install bundler
Fetching: bundler-1.2.0.gem (100%)
ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied - /var/lib/gems

Answer 1

Have you tried executing this as superuser?

sudo gem install bundler

Or, you could try changing the /var/lib/gems modes using chmod.

Answer 2

Add this to the bottom of .bashrc

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"  # This loads RVM
