RubyGems Dependency Error

My ruby version is => ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux] and I'm using Ubuntu 10.10. I installed every stuff following this blogpost. It was working fine on bash but when I installed zsh shell and oh-my-zsh then it started raising following dependency error:

/home/manish/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find rails (>= 0) amongst [minitest-1.6.0, rake-0.8.7, rdoc-2.5.8] (Gem::LoadError)
from /home/manish/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:256:in `to_spec'
from /home/manish/.rvm/rubi开发者_JS百科es/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems.rb:1210:in `gem'
from /home/manish/.rvm/gems/ruby-1.9.2-p290/bin/rails:18:in `<main>'

Please tell me if there is any way to fix this.

P.S. => I have installed bundler gem. I also tried to uninstall rvm and reinstall but didn't worked.

Oh crap this sucks. I already had rvm script

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

in my ~/.zshrc

but it use to say following error in my zsh shell every time:

cd:cd:10: string not in pwd: ..

then i rewrote the same script again following the previous one i.e. running same script twice in ~/.zshrc, it WORKED. I still could not figure it out why it raises string not in pwd.... error on first script and runs the second one.

But yay! feels good to finally use zsh on my Ubuntu also :)

From looking at your rvm info it seems that this isn't quite right:

  homes:
    gem:          "not set"
    ruby:         "not set"

I would have another crack at reinstalling rvm, it shouldn't be that difficult. If you're having problems then you can ask on the channel #rvm on the freenode IRC network.

Other things to try would be rvm reload followed by rvm 1.9.2.
