Manage your application's gem dependencies with less pain

Build Status

Bundler: a gem to bundle gems

Bundler is a tool that manages gem dependencies for your ruby application. It takes a gem manifest file and is able to fetch, download, and install the gems and all child dependencies specified in this manifest. It can manage any update to the gem manifest file and update the bundle’s gems accordingly. It also lets you run any ruby code in context of the bundle’s gem environment.

Installation and usage

See gembundler.com for up-to-date installation and usage instructions.


For help with common problems, see ISSUES.


To see what has changed in recent versions of bundler, see the CHANGELOG.

The master branch contains our current progress towards version 1.1. Because of that, please submit bugfix pull requests against the 1-0-stable branch.

Upgrading from Bundler 0.8 to 0.9 and above
