Heroku buildpack: Python

This is a Heroku buildpack for Python apps, powered by pip.

Usage

Example usage:

$ ls
Procfile  requirements.txt  web.py

$ heroku create --buildpack git://github.com/heroku/heroku-buildpack-python.git

$ git push heroku master
...
-----> Python app detected
-----> Installing runtime (python-2.7.8)
-----> Installing dependencies using pip
       Downloading/unpacking requests (from -r requirements.txt (line 1))
       Installing collected packages: requests
       Successfully installed requests
       Cleaning up...
-----> Discovering process types
       Procfile declares types -> (none)

You can also add it to upcoming builds of an existing application:

$ heroku config:add BUILDPACK_URL=git://github.com/heroku/heroku-buildpack-python.git

The buildpack will detect your app as Python if it has the file requirements.txt in the root.

It will use Pip to install your dependencies, vendoring a copy of the Python runtime into your slug.

Specify a Runtime

You can also provide arbitrary releases Python with a runtime.txt file.

$ cat runtime.txt
python-3.4.2

Runtime options include:

  • python-2.7.8
  • python-3.4.2
  • pypy-2.4.0 (unsupported, experimental)
  • pypy3-2.4.0 (unsupported, experimental)

Other unsupported runtimes are available as well.
