Solution 1:[1]

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.

Solution 2:[2]

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.

Solution 3:[3]

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.
