can't use bundle install

Question

I'm experiencing some difficulties when using the command: "bundle install". It's probably some kind of a trivial issue, but I would appreciate any help you can give. I am using linux ubuntu 11.04, ruby 1.9.3p125 (2012-02-16 revision 34643) [i686-linux]

The error message I get is this :

Answer 1

Being on Ubuntu, you might want to work on your app in /home/<username>/ where you should have more permissions. If you are working in the /var/ directory, you might need to use sudo everywhere.

Answer 2

Looks like bundler doesn't have rights to access Gemfile and/or Gemfile.lock make sure the permissions are right on those files.
