python - ImportError：无法导入 Django。蟒蛇路径

问题描述

有一个错误account.User尚未安装，但我解决了这个问题。之后，另一个错误说The SECRET_KEY setting must not be empty.

我不知道我解决这个问题的方法是否正确，我用谷歌应用了一些解决方案。但是现在，有一个错误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? 但是我已经安装了django和virtualenv。我不知道该怎么做。

最近的错误：

Traceback (most recent call last):
  File "/Users/leejunseo/PycharmProjects/ITM coding/manage.py", line 10, in main
    from django.core.management import execute_from_command_line
  File "/Users/leejunseo/PycharmProjects/ITM coding/venv/lib/python3.9/site-packages/django/core/management/__init__.py", line 12, in <module>
    from django.conf import settings
  File "/Users/leejunseo/PycharmProjects/ITM coding/venv/lib/python3.9/site-packages/django/conf/__init__.py", line 21, in <module>
    from .base import *
ModuleNotFoundError: No module named 'django.conf.base'

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

Traceback (most recent call last):
  File "/Users/leejunseo/PycharmProjects/ITM coding/manage.py", line 21, in <module>
    main()
  File "/Users/leejunseo/PycharmProjects/ITM coding/manage.py", line 12, in main

解决方案

您的回溯准确地告诉您出了什么问题：

无法导入 Django。您确定它已安装并在您的 PYTHONPATH 环境变量中可用吗？您是否忘记激活虚拟环境？

因此，您应该重新启动 IDE 或激活您的环境，因为 Django 无法启动
