Reinstalling rubygems

Question

How do you reinstall RubyGems as mentioned in no such file to load -- rubygems (LoadError)?

Running Mac OS X 10.8.2

Answer 1

Download it right from the source.

I had massive trouble trying to get gem update --system or gem install rubygems-update working properly.

The only thing that worked was downloading right from the source and just overwriting your old version of RubyGems.

1. Simply download the latest here (was 2.0.3 at time of writing).

2. Extract the downloaded archive and cd into the resulting directory.

3. Run the setup with ruby setup.rb. (You may need to use sudo for this, but try it without first.)

All good!
