Question

在命令后，在Heroku上部署Django应用程序时出现问题：

heroku run python manage.py migrate

我收到以下错误文本：

Traceback (most recent call last):
  File "manage.py", line 22, in <module>

  File "/app/.heroku/python/lib/python3.7/site-packages/django/core/management/__init__.py", line 364, in execute_from_command_line

import dj_database_url
ModuleNotFoundError: No module named 'dj_database_url'

当我运行pip freeze时，似乎已经存在 dj_database_url 。

我的点冻结给出了：

对于当前状态，我不知道错误的来源。我很茫然，我希望有人能够为此提供帮助并希望

在Heroku上部署Django应用时，没有名为“ dj_database_url”的模块
