Easily dump and restore a snapshot of installed gems
gem_snapshot is a small rubygems plugin that allows you to dump a snapshot of your installed gems to a YAML file, and then install the gems in the snapshot later on (probably on a different computer).

Or you can just use bundler which is self contained and accomplishes the same goal and more.
RVM also has this functionality built in
Nice gem, I should try and integrate it with LazyGem.
gem snapshot dump -f filename.ymldoesn’t seem to work on Windows XP. But you can just usegem snapshot dump > filename.ymlDoesn’t Bundler only do this on a per project basis? (And then requires you load Bundler in..)
When I first heard about Bundler, I hoped it was going to work like this rather than the.. weird way it does.
Bundler does not do this.
