Ruby Gems Area Not Writeable

I am on a Acer Chromebook and installed Ruby and Git through the Chromebrew package manager. After this, I tried to install Sass through gem install sass. When I type this, I get You don't have write permissions for the /usr/local/lib/ruby/gems/2.0.0 directory.. I tried making another directory but cannot seem to. Help?

Update: When I try using sudo gem install sass, I get this error:

ERROR: While executing gem ... (Errno::EROFS) Read-only file system - /root/.gem

Try prepending sudo to your gem install command to install it with admin privileges: sudo gem install sass.
