I'm trying to run a rake task on a rails app, and am getting this error:

/home/vagrant/.rbenv/versions/2.0.0-p195/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/definition.rb:361:in     `validate_ruby!': Your Ruby version is 1.9.3, but your Gemfile specified 2.0.0 (Bundler::RubyVersionMismatch)

rake aborted!

As you can see from the paths in the error though, I am running 2.0.0:

$ ruby -v
ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-linux]

$ bundle -v
Bundler version 1.3.5

$ gem env

I tried doing rbenv global 2.0.0-p195, but that didn't help. Looks like it might be trying to use system ruby instead of rbenv for some reason?

Raised an issue with bundler: rubygems/bundler#2489 but it seems to be an rbenv issue.

rake is a rbenv shim at: ~/.rbenv/shims/rake

Thanks,
