django - ImportError：在 CMD 中运行“heroku python manage.py migrate”后无法导入 Django

问题描述

在 CMD 中运行“heroku python manage.py migrate”后出现以下错误。

C:\Users\ky2001\Desktop\my_app>heroku run python manage.py migrate
Running python3 manage.py migrate on ⬢ leadersbooks... up, run.6589 (Free)
Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    from django.core.management import execute_from_command_line
ModuleNotFoundError: No module named 'django'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "manage.py", line 16, in <module>
    ) from exc
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

我已经尝试过
1.删除“ Pipfile”并再次
运行 2.heroku python manage.py makemigrations首先运行“”
3.更改python为python3
4.重新部署应用程序
5.（我的 requirements.txt 文件，Procfile 和 Pipdile 直接在根目录中）

但他们都没有工作。
我的 requirements.txt 中有 django，

如果您有任何解决方案，请帮助我。

我的代码如下。

web: gunicorn personal_portfolio.wsgi --log-file -

解决方案

我没有创建 Procfile。我以为我是通过运行来完成的，web: gunicorn gettingstarted.wsgi但我需要创建一个包含此代码的文件。
