On a VPS I tried to install Ruby. Because of memory exhaustion problems, we were unable to compile ruby 1.9.2 , and we decided to give Ruby Enterprise Edition a try. This compiled without complaining about memory problems.
Next, we install rubygems, and to test that it's working, I installed haml. It worked.
The next step was to install rails, via gem install rails. The version it downloaded was the latest, 3.0.5. Installation went ok. However, when I try to create a new project, I receive:
no such file to load -- rails/cli
Looking around on the internet, people said this is a problem related to older versions of rails, and some of them suggested to do a gem clean. I didn't have any other version of ruby before, therefore, no other version of rails. But, just to be sure, I did a gem clean and then reinstalled rails. The problem persists.
How can I fix this?
Make sure your running the gem binary that Ruby Enterprise Edition installed. So rather than:
gem install rails
it would be something like:
sudo /opt/ruby-enterprise-X.X.X/bin/gem install rails
To save having to type the whole path each time, you can symlink the REE binaries with something like:
sudo ln -sf /opt/ruby-enterprise-X.X.X/bin/* /usr/bin/.
