The official heroku python buildpack has pip 8 included by default. You should use it an the new requirements file with hashes format.
The only additional thing you need to do to use this over the official Heroku Python buildpack is to add the hashes to your requirements file(s) so that peep will successfully complete the install. If you don't do this peep will fail and give a good explanation as to why.
$ ls Procfile requirements.txt web.py $ heroku create --buildpack git://github.com/pmclanahan/heroku-buildpack-python-peep.git $ git push heroku master ... -----> Python app detected -----> Installing runtime (python-2.7.10) -----> Installing dependencies using peep Downloading requests==2.7.0 (470K)... Processing /tmp/peep-PWtR4d/requests-2.7.0-py2.py3-none-any.whl Installing collected packages: requests Successfully installed requests-2.7.0 Cleaning up... -----> Discovering process types Procfile declares types -> (none)
You can also add it to upcoming builds of an existing application:
$ heroku buildpacks:set git://github.com/pmclanahan/heroku-buildpack-python-peep.git
The buildpack will detect your app as Python if it has the file
requirements.txt in the root.
It will use Peep to install your dependencies, vendoring a copy of the Python runtime into your slug.
You can also provide arbitrary releases Python with a
$ cat runtime.txt python-3.5.0
Runtime options include:
Other unsupported runtimes are available as well.
Copy the snippet above into CLI.
