       Dependencies installed

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

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

This buildpack also checks for Node.js, for usage see:

https://github.com/heroku/heroku-buildpack-nodejs

Specify a Runtime

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

$ cat runtime.txt
python-3.3.0

Runtime options include:

• python-2.7.4
• python-3.3.1
• pypy-1.9 (experimental)
