我是heroku以及python（Django）的新手。我在django做了一个应用程序，想要推进heroku。但在git push heroku master它给了我这个错误。

我有requirements.txt文件和runtime.txt文件。 runtime.txt 看起来像这样
Python-2.7.13
和 requirements.txt 看起来像这样
BestBuyAPI==0.0.51
dj-database-url==0.4.2
Django==1.9
django-cors-headers==2.0.2
djangorestframework==3.6.2
djangorestframework-jwt==1.10.0
ebaysdk==2.1.4
gunicorn==19.7.1
lxml==3.7.3
psycopg2==2.7.1
PyJWT==1.5.0
pytz==2017.2

当我用python版本3.5.x更改runtime.txt时，它可以运行。但由于某些原因，我必须使用python 2.7.x. 任何人都可以回答这个问题。任何建议或帮助都会受到高度关注。
