Gemtracker

Gemtracker makes sure your Rails application uses the same gems and versions, no matter where it’s deployed.

All you have to do is specify a list of gems in “config/gems.yml”. When script/server or script/console is run, Gemtracker ensures that all the gems are present and at the correct version, throwing an exception if they can’t be found.

Gemtracker comes with a rake task, “gems:install”, which installs all gems listed in “config/gems.yml” at the specified versions, if not already present.

Example

config/gems.yml:

mongrel: 1.0.1
rspec  : 1.0.0
facets : 0.4
foobar : 0.1.0

Using fuzzy versions as supported by Rubygems should work, but is not encouraged. After all, you’re trying to make sure that everyone has the same gems and versions, right?
