Updating Gemfile.lock without installing gems

Is there a way to force an update of the Gemfile.lock without installing the gems that have changed?

Solution

  • Run bundle lock --update.

    I found an answer in a blog post by Chris Blunt: “Rails on Docker: Quickly Create or Update Your Gemfile.lock”:

    Today, I discovered a way to save the hours wasted downloading gems: bundler’s lock command.

    This gem of a command resolves your app’s dependencies and writes out the appropriate Gemfile.lock – without installing any of the gems themselves.

    According to the changelog, this command was added in Bundler 1.10.0.pre, released about eight months after this question was asked.
