How I did all Wrong
- I had ruby 1.8.7 and Installed RVM as ROOT, not the gem
- I did the above without knowing about the working of RVM
- I had ruby 1.8 and 1.9 installed, and the gem had a confused env
- Lots of other confusing paths and installs
Now, the good part.. Simple rails 3.0 install
How I did it work*:
- Removed RVM by the great command sudo rvm implode
- Also ruby1.9, sudo aptitude remove ruby1.9
- Updated my gems:
sudo gem install rubygems-update
gem env | grep 'EXECUTABLE DIRECTORY'
sudo `gem env | grep 'EXECUTABLE DIRECTORY' | ruby -e "puts gets.split(': ', 2).last"`/update_rubygems
- Installed Rails 3.0.0, sudo gem install rails -v3.0.0
- Made a project on rails, rails new dum; cd dum
- Installed mysql gem, bundle install
- rails server

*: I have not tried it for real, with several gems, I will update if anything fails It is all working just fine
