Update Python setuptools on Heroku

Is it possible to update Python setuptools on Heroku?

I get this error when deploying to Heroku:

remote:        ERROR: google-auth 1.18.0 has requirement setuptools>=40.3.0, but you'll have setuptools 39.0.1 which is incompatible.

You can add the line setuptools==40.3.0 to your requirements.txt file and it will work.

You could also try to update your python version in the runtime.txt file because I think heroku update setuptools directly with python module updates.

The version of setuptools appears to be hard-coded into the heroku/python buildpack, with the latest release (tagged as v170) using setuptools-39.0.1. The master branch shows the same thing, so I don't expect to see an official release upgrading setuptools anytime soon.

The easiest solution might be to use an older version of google-auth that doesn't require newer setuptools. v1.6.3 looks like it should work.

You could try explicitly depending on setuptools>=40.3.0 in your requirements.txt or Pipfile, though I'm not sure how well that will work.

Or you could fork the heroku/python buildpack, modify it, and use it, though the maintenance burden of doing so is likely to be high. There might even be an existing third-party buildpack that does what you want, though I didn't see one on a quick search.
