I'm using Ubuntu 10.10 64bit and have just switched over to using ZSH today. After I logged out and back in to load the new zsh I experienced this problem:

/home/map7/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/1.9.1/rubygems.rb:762:in `report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError) from /home/map7/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/1.9.1/rubygems.rb:219:in `activate' from /home/map7/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/1.9.1/rubygems.rb:1065:in `gem' from /home/map7/.rvm/gems/ruby-1.9.2-p136/bin/rails:18:in `<main>'

This problem is very similar to: Install Rails 3 on OSX with RVM

I have fixed the problem using the answer from that post but I would like to know if I'm doing this correctly and if there is a better way?

After completing these steps (thanks to marshally):

rvm update && rvm reload rvm gemset delete rails3 rvm install 1.9.2 rvm use 1.9.2 rvm gemset create rails3 gem install rails rvm use 1.9.2@rails3

Then I entered command

$ rvm use 1.9.2 --default

I still had to add the following to my .zshrc file:

[[ -s $HOME/.rvm/scripts/rvm ]] && source $HOME/.rvm/scripts/rvm rvm use 1.9.2@rails3

Should I have to enter these lines into the .zshrc for it to work? It seems like a work around?

I have tried 'rvm use 1.9.2@rails3 --default' but the problem still happens when opening a new terminal.

Reset to default

You shouldn't need the rvm use 1.9.2@rails3 line in your .zshrc.

I believe the problem mentioned in that post has been fixed in the current version of RVM, so that shouldn't be an issue anymore. With only the [[ -s $HOME/.rvm/scripts/rvm ]] && source $HOME/.rvm/scripts/rvm in your .zshrc, do you get the original error message, or is it just that your default gemset is not set?

I can remove the rvm use 1.9.2@rails3 but I must have these two lines in the .zshrc: '[[ -s $HOME/.rvm/scripts/rvm ]] && source $HOME/.rvm/scripts/rvm' and 'rvm 1.9.2'
I also noticed that I had rails installed in the /usr/bin/rails directory to, which was never a problem when using bash. So I had to switch over to rvm system and uninstall that gem.
I no longer need the 'rvm use 1.9.2@rails3'. It could be that I've updated my packages a few times since this question and most likely RVM as part of that and the problem has gone away.
