This is a completely unofficial Heroku buildpack for Python apps that need Buildout, for some reason. It uses virtualenv and pip.
Example usage:
$ ls
Procfile bootstrap.py buildout.cfg
$ heroku create --stack cedar --buildpack [email protected]:kennethreitz/heroku-buildpack-buildout.git
$ git push heroku master
something.
The buildpack will detect your app as Buildout if it has the file buildout.cfg 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.
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.
