将烧瓶应用程序部署到heroku错误 [英] deploying flask app to heroku error

问题描述

直到今天它给我这样的错误，我已经将这个特定的应用程序多次推向heroku了，直到今天它没有出现任何问题

I have pushed this particular app so many times to heroku without any issues until today when it gave me errors like this

error: failed to push some refs to 'https://git.heroku.com/serene-temple-30062.git'

然后我将runtime.txt更改为python-3.6.0，因为那是受支持的运行时，现在我得到了这样的错误

Then i changed the runtime.txt to python-3.6.0 since that was the supported runtime now i get errors like this

请提供任何帮助，谢谢

推荐答案

我最近遇到了这个问题.这似乎是一个问题，尤其是对于appdirs.我已经解决了这个问题，只需升级appdirs，更新我的requirements.txt文件，然后重新部署到heroku.

I faced this issue recently. This seems to be an issue particularly with appdirs. I've resolved this issue by just simply upgrading appdirs, updating my requirements.txt and then redeploying to heroku.

pip install appdirs --upgrade
pip freeze > requirements.txt
