Bundler cannot install any gems without sudo

I'm trying to install a rails app and every time I use bundle it fails without sudo. My current situation is that everything works as long as use sudo for everything, including rails. I don't think this is correct.

For example:

$ bundle update
Updating git://github.com/refinery/refinerycms.git
Fetching gem metadata from https://rubygems.org/.......
Fetching gem metadata from https://rubygems.org/..
Resolving dependencies...
Enter your password to install the bundled RubyGems to your system: 
Using rake (10.0.4) 
Using i18n (0.6.1) 
Using multi_json (1.7.2) 
Using rack-cache (1.2) 
Using rack-test (0.6.2) 
Installing hike (1.2.2) 
Errno::EACCES: Permission denied - /usr/local/rvm/gems/ruby-1.9.3-p194/build_info/hike-1.2.2.info
An error occurred while installing hike (1.2.2), and Bundler cannot continue.
Make sure that `gem install hike -v '1.2.2'` succeeds before bundling.

But then I do what it says and it works:

$ gem install hike -v '1.2.2' 
Successfully installed hike-1.2.2
Parsing documentation for hike-1.2.2
Installing ri documentation for hike-1.2.2
Done installing documentation for hike after 0 seconds
1 gem installed

This pattern repeats again and again for different gems. I don't get it. Why is this happening? If I use sudo bundle will update without this error. But the current situation is that I need sudo for everything, including rake... or rails server, etc. Something isn't right.

Additional details: I'm on OSX 10.8.3...

Update

It may be informative that I can run sudo bundle install with no errors. Then immediately after bundle install fails with an error like you see above. Why is this?

You may host gems in your user home folder, that does not need root permissions:

bundle install --path ~/.gem

To avoid passing this parameter manually add export GEM_HOME=$HOME/.gem to your .bash_profile -- this solves sudo issue on Mac OS and other *nix systems. You then also might need to have access to gems that provide executables (such as bundler), so add this too:

PATH=$PATH:$HOME/.gem/bin

or in some cases:

PATH=$PATH:$HOME/.gem/ruby/<version>/bin

UPD: But keep in mind that if you start using rbenv having this environment variable be the same might cause problems when using too different versions of Ruby, so you might want to temporary unset GEM_HOME or prepend custom one each time you launch rbenv-ed Ruby.


Your RVM gem directory should be owned by the rvm group. So, instead of changing ownership, it might be wise to simply add the user to the rvm group:

# $(whoami) evaluates to your username
# You may want to change this to a different username depending on your config
# but $(whoami) is a passable default
usermod -a -G rvm $(whoami)
