Question

I recently ran ‘bundle update,’ and it updated the Twitter-bootstrap-rails gem to the latest version. Ever since then, the header size has changed, and I would like to roll back to the previous gem versions for all my gems.

I tried rolling back to my previous gemfile and bundle updating, but the problem was I didn’t specify versions in my gemfile so it doesn’t know to degrade a version. I also tried checking the specific previous version and specifying that, but I think all the dependencies changed as well.

So I need to find a way to just go back to using all the old versions, which seems to be stored in the Gemfile.lock file. How would I do this?

Answer 1

you can easily go back to a version of any file that you track in git with

git checkout <some-ref> -- path/to/your/file

where some-ref is

HEAD^
HEAD~5
v1.2
some-branch

etc
