问题
I use bundler to manage dependencies in my rails app, and I have a gem hosted in a git repository included as followed:
gem 'gem-name', :git => 'path/to/my/gem.git'
To update this gem, I execute bundle update but it also updates all the gem mentioned in Gemfile. So what is the command to update just one specific gem?
回答1:
Here you can find a good explanation on the difference between
Update both gem and dependencies:
bundle update gem-name
or
Update exclusively the gem:
bundle update --source gem-name
along with some nice examples of possible side-effects.
Update
As @Tim's answer says, as of Bundler 1.14 the officially-supported way to this is with bundle update --conservative gem-name.
回答2:
The way to do this is to run the following command:
bundle update --source gem-name
回答3:
You simply need to specify the gem name on the command line:
bundle update gem-name
回答4:
It appears that with newer versions of bundler (>= 1.14) it's:
bundle update --conservative gem-name
回答5:
bundle update gem-name [--major|--patch|--minor]
This also works for dependencies.

I've used bundle update --source myself for a long time but there are scenarios where it doesn't work. Luckily, there's a gem called bundler-patch which has the goal of fixing this shortcoming.
I also wrote a short blog post about how to use bundler-patch and why bundle update --source doesn't work consistently. Also, be sure to check out a post by chrismo that explains in great detail what the --source option does.

bundler update --source gem-name will update the revision hash in Gemfile.lock which you can compare with the last commit hash of that git branch (master by default).
