Rails is Nuked - How to Reinstall

Question

I've just spend about 3 hours trying to reinstall a nuked Rails installation. It stopped working after trying to install the "authlogic" gem (which, btw, if anyone has any idea how to install that, PLEASE let me know).

OLD PROBLEM

The steps were something like this: 1. Nuke Rails after typing "sudo gem install authlogic" 2. Try removing ~/.rvm, still doesn't work 3. Using gem uninstall, remove ALL gems until nothing shows in gem list --local 4. sudo gem install rails

Now, "rails" works, but only outside a Rails project. Whenever I go into a rails app and run rails server, I get the following:

Could not find rake-0.9.2.2 in any of the sources

So apparently rake is gone. But only inside a Rails project (even a new one!). Both rails and rake work, but both fail if I'm cd'd to a Rails project directory.

I'm on Mac OS 10.7.3 and everything worked perfectly up until using sudo gem install authlogic.

Answer 1

The difficulty here is likely bundler doesn't realize all these gems are gone. Try going into your Rails directory and doing 'bundle install'; this should result in all your gems returning.
