how to install gems without sudo

Question

On all my gem installs I have to do sudo ? So

sudo gem install rails

will work, while only

gem install

Answer 1

Use chown on the whole .rvm and .gem directories back to your user. You probably used sudo before and it screwed up permissions.

sudo chown -R username:group ~/.rvm
sudo chown -R username:group ~/.gem

Of course, change username to your username and group to your group
