Should rbenv be installed system-wide, or at a user level?

Question

I\'m building a vagrant setup, and part of that is installing rbenv. I\'m using librarian-chef to manage all my chef cookbooks, and it installs rbenv and ruby-build.

Answer 1

rbenv should be installed at a user level.

Unfortunately, this means that when running gem install, you may run into the problem you saw:

You don't have write permissions into the {...} directory

You can solve this by setting the correct permissions on the ~/.rbenv directory.

sudo chown -R yourusername ~/.rbenv

After chowning the directory, you'll be able to run gem install without sudo.
