rbenv-binstubs: A Bundler binstubs Plugin for rbenv

This plugin makes rbenv transparently aware of project-specific binstubs created by bundler.

This means you don't have to type bundle exec ${command} ever again!

Build Status of master


To install rbenv-binstubs, clone this repository into your ~/.rbenv/plugins directory. (You'll need a recent version of rbenv that supports plugin bundles.)

$ git clone https://github.com/ianheggie/rbenv-binstubs.git "$(rbenv root)/plugins/rbenv-binstubs"

Then for each application directory run the following just once:

$ bundle install --binstubs .bundle/bin
$ rbenv rehash

The .bundle/bin argument keeps the binstubs separate from the default bin/ since bin/ is now used for application scripts and should be included in your code repository (from rails 4.0.0 onwards). If you wish to mix application scripts and binstubs, then consider generating only those binstubs you need.

I recommend you also install the gem-rehash plugin as well so you don't have to remember to use rbenv rehash after each bundle install. Note gem-rehash only calls rbenv rehash if a new gem executable is installed, so you will need to run rbenv rehash for each project directory after installing this plugin or for the specific project if you change the binstub directory.


Simply type the name of the command you want to run! Thats all folks! Eg:

$ rake --version

This plugin searches from the current directory up towards root for a directory containing a Gemfile. If such a directory is found, then the plugin checks for the desired command under the 'bin' sub-directoy. If you used bundle --binstubs=some/pib/path then that directory will be checked instead of 'bin'.

To confirm that the bundler binstub is being used, run the command:

$ rbenv which COMMAND

To show which gem bundle will use, run the command:

$ bundle show GEM

You can disable the searching for binstubs by setting the environment variable DISABLE_BINSTUBS to a non empty string:

$ DISABLE_BINSTUBS=1 rbenv which command

You can list the bundles (project directories) and their associated binstub directories that have been registered since the plugin was installed using the command:

$ rbenv bundles

This will add a comment if bundle is not set to automatically create binstubs, or the binstubs directory is missing, or if a Gemfile no longer exists. If the Gemfile for a bundle is removed, then that bundle will be dropped from the list of bundles to check when rbenv rehash is next run.

rbenv-bundler is another rbenv plugin for bundler - it makes shims aware of bundle installation paths. It uses a more involved approach which has performance and other consequences.

Note on Patches/Pull Requests

Since I no longer using rbenv, I am happy to include pull requests, but I am not actively developing this plugin. If you are interested in taking on this project, either completely or in partnership, please contact me.

  • Fork the project.

  • Send me a pull request. Bonus points for topic branches.


Thanks go to:

  • madumlao - contributed code so this plugin now creates shims for all the executable files in the binstubs directory, thus bundle --path=vendor/bundle ... is now handled, as are arbitrary executables in the binstubs directory.
