Update just one gem with bundler

sailor picture sailor · Jun 29, 2012 · Viewed 114.4k times · Source

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?

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.
