bundle outdatedto print a list of gems that could be upgraded.
If you want to upgrade a specific gem, run
bundle update GEMor run
bundle updateto update everything. After the update finishes, make sure all your tests pass before you commit your new
bundle update won't just install gems -
it will try to upgrade every single gem in your bundle.
That's usually a disaster unless you really meant to do it.
update command is for when gems you use has been updated,
and you want your bundle to have the newest version that your
[~/ruby/faye]$ bundle help outdated Usage: bundle outdated [GEM] Options: [--pre=Check for newer pre-release gems] [--source=Check against a specific source] [--local=Do not attempt to fetch gems remotely and use the gem cache instead] [--no-color=Disable colorization in output] -V, [--verbose=Enable verbose output mode] Description: Outdated lists the names and versions of gems that have a newer version available in the given source. Calling outdated with [GEM [GEM]] will only check for newer versions of the given gems. Prerelease gems are ignored by default. If your gems are up to date, Bundler will exit with a status of 0. Otherwise, it will exit 1.

Bundler uses your
to create what is technically called a dependency graph,
where there are many gems that have various dependencies on eachother.
It can be pretty cool to see that dependency graph drawn as a literal graph, and that's what the
bundle viz command does.
You need to install
GraphViz and the
$ brew install graphviz # for mac os X. apt-get for Linux $ gem install ruby-graphviz $ bundle vizOnce you've done that, though, you get a pretty picture that's a lot of fun to look at. Here's the graph for a Gemfile:

Gemnasium https://gemnasium.com is a service that learns your gem dependencies, listens for new versions of those gems and notifies you when they’re released.
Gemnasium sends you an email whenever a new version is released for a gem that you use. You can turn off notifications for particular gems or for entire repositories, or choose to receive them in a digest email on a daily or weekly basis.
Gemnasium represents the statuses of your dependencies with three colors:
Gemnasium looks the Gemfile.lock files. If your repository has one, Gemnasium will use it. They’re informational and easily parsed with a little help from Bundler.
Unfortunately, it’s not always wise to commit your Gemfile.lock. In those cases, Gemnasium looks for a Gemfile instead.
If all else fails, Gemnasium looks for a gemspec file in your repository’s root directory.
If any of these files exists, Gemnasium parses them to determine your repository’s gem dependencies.
