Cleaning up...
|
|
|
|
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-3.3.3
|
|
|
|
Runtime options include:
|
|
|
|
- python-2.7.6
|
|
- python-3.3.3
|
|
- pypy-1.9 (experimental)
|
|
|
|
Other [unsupported runtimes](https://github.com/kennethreitz/python-versions/tree/master/formula) are available as well.
