Try this

Create a .gemrc file in your home directory (~) to declare GEM_PATH
and GEM_HOME, this is in yaml format.
Replace the gempath with whatever the path is on your machine if its
different.

# add what is below
gemhome: /home/yourusername/gems
gempath:
- /home/yourusername/gems
- /usr/lib/ruby/gems/1.8


Verify the environment has changed with:

$ gem environment

Hope this helps
