Heroku“推送被拒绝，无法编译Python应用”

Question

I'm trying to push my Flask web application to Heroku but get the following error when I try to push to Heroku:

Fetching repository, done.

Compressing objects: 100% (3/3), done.

It looked like this had a solution to my problem so I removed distribute from my requirements.txt.

When I do that, I can push to Heroku. But the website just has "Application Error", as shown below.

My requirements.txt is:

Flask==0.9
Jinja2==2.6
Werkzeug==0.8.3
gunicorn==0.17.2
virtualenv==1.8.4

My Heroku Logs are:

I forgot to add a Procfile for Heroku. It needed to be:

web: gunicorn app:app
