There is one obvious way:

git checkout -- Gemfile.lock

and then run

bundle install

It assumes you use git - but who does not now days, I have everything in git.

git checkout by default tries to checkout git branch, if you specify `--` it knows it has to checkout files ... it's only in case you would have a branch named the same as one of your files - but it's a good habit. – mpapis Mar 12 '12 at 15:30

I went into Github, copied my old Gemfile.lock that I wanted and pasted it into my Gemfile.lock in my code and then ran bundle install.

I tried to follow the accepted answer but I was still getting errors. This is what worked for me:

git checkout -- Gemfile.lock

And then:

bundle pristine

As described in the Bundler docs, bundle pristine restores installed gems to their pristine condition.
