Error running ROR commands in Textmate

When I try to run some of the commands in the Ruby on Rails Textmate bundle, I get the following error:

"Could not find activesupport-3.0.1 in any of the sources Try running 'bundle install'"

I have run 'bundle install' and it indicates activesupport is installed.

I have also tried running gem install activesupport -v 3.0.1

What could be c开发者_如何学运维ausing this error?

Are you by any chance using RVM in the mix too?

TextMate would be using the system Ruby - if this is the case you need to use the textmate wrapper for RVM details here
