Answer 1

Even though running sudo bundle install should help as suggested by @ProperSharp, it does not solve the cause of the problem. The cause of the problem is that your current user doesn't have permissions. Most probably to rvm or rvm's gemset folder. RVM expects current user to own gem directory.

You need to find that folder and chown it. Alternatively, use the following RVM commands to do that for you:

# General environment repairs
rvm repair

# Fixes issues with folder/file permissions
rvm fix-permissions

The second command should help.

Answer 2

Type SUDO before the command.

You are having a permission error.
