In Rails, why there is a new Gemfile.lock when no bundle or bundle install was run? (and a new Gemfile timestamp too)

It is very strange that all of a sudden, there is a new Gemfile.lock in my folder, even though I have not run bundle or bundle install or bundle update for a few days.

Also, I have merged in any changes and committed and pushed 1 ho开发者_JS百科ur ago, so this newly modified Gemfile.lock seems weird.

Also, the timestamp of Gemfile is just 1 minute before the timestamp (modification time) of Gemfile.lock, but I checked the Mercurial log and Gemfile was modified 3 days ago, and I pull any new changes 12 hours ago and there wasn't any change...

So why a new timestamp of Gemfile, and why is Gemfile.lock also modified?

You could try running "bundle install" again, and see if it will change your Gemfile.lock file.
