关于django：ImportError：在Heroku上部署时，没有名为“ decouple”的模块

ImportError: No module named 'decouple' while deploying on Heroku

我试图在heroku CLI的heroku上部署django项目。因此，我创建了一个应用程序，然后从项目目录中运行了git push heroku master。然后我得到了错误：

remote: You may need to update application code to resolve this error.
remote: Or, you can disable collectstatic for this application: remote:
remote: $ heroku config:set DISABLE_COLLECTSTATIC=1
remote:
remote: https://devcenter.heroku.com/articles/django-assets
remote: ! Push rejected, failed to compile Python app.
remote:
remote: ! Push failed

如前所述，我运行了heroku config:set DISABLE_COLLECTSTATIC=1。
然后将代码推送到存储库中。然后我运行了heroku run python3 manage.py migrate。但是我仍然遇到同样的错误：

File"/app/funderpreneur/settings.py", line 15, in

from decouple import Csv, config ImportError: No module named 'decouple'

但是我在本地为python 2和python 3安装了python-decouple，而且整个项目都在Django版本2和python版本3.5.2上运行。但是在runtime.txt中，我设置了python-3.6.4。我有requirements.txt，其中decouple已经存在。

在我的settings.py中，

1 2	import django_heroku django_heroku.settings(locals())

但是我遇到了错误，因此我对它们进行了评论。仍然出现错误。

错在哪里或我在做什么错？
