RVM /降级捆绑器gem

Question

I have the following interesting scenario:

I've install ruby 1.9.2 via RVM and it came prepackaged with bundler 1.1.4.

My application requires bundler 1.0.15.

I've tried running the following:

gem uninstall bundler

I get the following:

INFO:  gem "bundler" is not installed

Any thoughts how can downgrade my bundler?

Thanks.

Answer 1

Found the solution.

Apparently rvm installs it's gems in the global gemspec which is visible to all gemspecs.

So by doing:

rvm use 1.9.2@global

And followed by:

gem uninstall bundler

Does the trick.

This can be also shortened to:

rvm @global do gem uninstall bundler

Answer 2

Try add the following to .bash_profile

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

Or try to link the bundle to RVM bin dir

ln -s ~/.rvm/gems/ruby-1.9.2-p290@fonista/bin/bundle ~/.rvm/bin/
