I ran into trouble on Ubuntu 7.10 and had to reinstall Ruby, It wasn’t smooth sailing, so here is what I did to make ruby and gems work again:
- sudo apt-get remove gem
- sudo apt-get remove ruby
- rm -rf /var/lib/gems
- rm -rf /usr/lib/ruby
- sudo apt-get install ruby
- sudo apt-get install rubygems
- sudo apt-get install irb
- sudo apt-get install ri
- sudo apt-get install rdoc
- sudo apt-get install ruby1.8-dev
- sudo apt-get install build-essential
- sudo gem install rake
- sudo apt-get install rake
- sudo gem install ruby-debug-ide
- sudo gem install hpricot -v 0.5
- sudo gem install activesuport
- sudo gem install builder
- sudo gem install hoe
- sudo gem install rspec
- sudo gem install ruby-debug-base
- sudo gem install ruby-debug-ide
