Heroku部署问题-Python版本

Question

I have been working on a Django project that I am trying to deploy to Heroku. I've followed a tutorial from Python Crash Course. When I enter git push heroku master, I get the following as a response:

Counting objects: 73, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (65/65), done.

When I Python --version the cmd line returns 2.7.14 which is the most up-to-date version. I feel like this error is telling me I need to use Python3 but their site says that 2.7.14 is supported as well. My runtime.txt specifies 2.7.14.

请在runtime.txt中尝试python-3.5.2，尽管它给出了警告，但仍然可以使用
