Push rejected, failed to compile Python app

Question

I'm getting a rejected error when trying to deploy a Django app to Heroku. I looked at possible solutions here:

1. Heroku push rejected, failed to compile Python/django app (Python 2.7)

2. Error pushing Django project to Heroku

But neither worked for me.

This is my flow from initiating the push to heroku:

git push heroku master

I've followed the instructions from the Heroku website. Any idea what I'm missing?

Answer 1

This is apparently a bug in the distribute package, which doesn't seem likely to get fixed:

Distribute is now considered deprecated and replaced by setuptools. I suggest replacing 'distribute==0.6.28' in requirements.txt with 'setuptools==1.0' or similar. The latest versions of pip (>=1.4) and setuptools (>=0.7) have better support for the unified code and upgrades and seek to obviate issues like the one encountered here.
