This is a Heroku buildpack for Python apps with added support for Gem and Node package dependencies.
It uses:
Additional (optionally) included libraries:
Example usage:
$ ls
Procfile requirements.txt Gemfile Gemfile.lock web.py
$ heroku create --buildpack git://github.com/localmed/heroku-buildpack-python-extras.git
$ git push heroku master

-----> Installing node packages using npm version 1.0.106
...You can also add it to upcoming builds of an existing application:
$ heroku config:add BUILDPACK_URL=git://github.com/localmed/heroku-buildpack-python-extras.git
The buildpack will detect your app as Python if it has the file requirements.txt in the root. It will detect your app as Python/Django if there is an additional settings.py in a project subdirectory.
It will use virtualenv and pip to install your dependencies, vendoring a copy of the Python runtime into your slug. The bin/, include/ and lib/ directories will be cached between builds to allow for faster pip install time.
If your project contains a Gemfile, bundler will be used to install Gem dependencies.
If your project contains a package.json, npm will be used install Node dependencies.
To use this buildpack, fork it on Github. Push up changes to your fork, then create a test app with --buildpack <your-github-url> and push to it.
To change the vendored virtualenv, unpack the desired version to the src/ folder, and update the virtualenv() function in bin/compile to prepend the virtualenv module directory to the path. The virtualenv release vendors its own versions of pip and setuptools.
