The solution is to run bundle install with --development (this is installation system wide / in verndor/rails)

Look here

mayee the problem is that i run foreman under root and not foreman

I solved this by running "bundle install --path vendor/" in /usr/share/foreman (Debian Squeeze). I need to check if that's a valid method from a clean Debian install though...

Hi,

I'm running Ubuntu 10.04. The fix doesn't work for me. :(

Restarting Apache after:

bundle install --path vendor/

gives me a new error:

Puppet is not missing constant Resource!

Thanks to Ohad:

echo "gem 'puppet'" >> Gemfile
bundle install --path vendor

fixed it.
