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.

Gem Dependencies

If your project contains a Gemfile, bundler will be used to install Gem dependencies.

Node Dependencies

If your project contains a package.json, npm will be used install Node dependencies.

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-2.7.3
• python-3.3.0
