This buildpack differs from the standard Heroku buildpack in that it supports deploying the latest version of Python built with shared libraries; this is required to build OpenCV on top of it to support our OpenCV buildpack, which installs the OpenCV Python package.
Deploying a Python application couldn't be easier:
$ ls Procfile requirements.txt runtime.txt web.py $ heroku create --buildpack git://github.com/heroku/heroku-buildpack-python.git $ git push heroku master ... -----> Python app detected -----> Installing python-2.7.11 $ pip install -r requirements.txt Collecting requests (from -r requirements.txt (line 1)) Downloading requests-2.9.1-py2.py3-none-any.whl (501kB) Installing collected packages: requests Successfully installed requests-2.9.1 -----> Discovering process types Procfile declares types -> (none)
requirements.txt file must be present at the root of your application's repository.
runtime.txt file is required to select the appropriate runtime (see below); the default is not available in this fork.
You can also specify the latest production relase of this buildpack for upcoming builds of an existing application:
$ heroku buildpacks:set heroku/python
Specific versions of the Python runtime can be specified with a
$ cat runtime.txt python-3.5.1
Runtime options include:
python-2.7.11-shared(same, but built as a shared library)
Other unsupported runtimes are available as well. Use at your own risk.
Copy the snippet above into CLI.
