"Bundler:GemNotFound" error in Autotest re: Thor

Question

EDIT: I rolled back to Thor 0.17.0 and that seemed to work. Not sure why, but there it is.

I can figure out what caused this, but my autotest stopped running tests and gave me the following error:

I've seen some similar problems on SO regarding GemNotFound errors, but the solutions don't seem to work for this. When I run bundle exex gem list Thor 0.18.0 is present.

Answer 1

Solution was to roll back to Thor 0.17.0

Answer 2

I've just had a similar problem when running a rake task, and done the following to fix the issue.

In your gemfile change the source from https to http://rubygems.org, and run bundle install.

My rake task then worked, not entirely sure why this occurred as im pretty sure both my dev machines are setup identically.
