Django 项目运行 manage.py 导致没有名为 django 的模块

Question

I was working on a django project served as a backend for a small personal site, the built-in localhost server by django runs smoothly until I accidentally removed the app execution alias of python in windows 10(It just happened after done that, might not成为罪魁祸首）。 情况是当我使用manage.py时，它总是导致一个名为“django”的模块

(venv) C:\Users\hongl\PycharmProjects\fluentdesign>manage.py runserver
Traceback (most recent call last):
  File "C:\Users\hongl\PycharmProjects\fluentdesign\manage.py", line 11, in main
    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 "C:\Users\hongl\PycharmProjects\fluentdesign\manage.py", line 22, in <module>
    main()
  File "C:\Users\hongl\PycharmProjects\fluentdesign\manage.py", line 13, in main
    raise ImportError(
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHO
NPATH environment variable? Did you forget to activate a virtual environment?

我试图解决它一点，只是困惑地发现已经激活了 venv 的终端在运行时总是连接到系统级 python ，其中没有安装 django。 以下是来自 venv 的 python 控制台：

(venv) C:\Users\hongl\PycharmProjects\fluentdesign>python
Python 3.8.9 (tags/v3.8.9:a743f81, Apr  6 2021, 14:02:34) [MSC v.1928 64 bit (AMD64)] on win

C:\Users\hongl\PycharmProjects\fluentdesign
C:\Users\hongl\AppData\Local\Programs\Python\Python38\python38.zip

C:\Users\hongl\AppData\Local\Programs\Python\Python38
C:\Users\hongl\PycharmProjects\fluentdesign\venv
C:\Users\hongl\PycharmProjects\fluentdesign\venv\lib\site-packages

我只想通过manage.py知道django内置服务器发生了什么，为什么我不能用venv中的python运行它，它安装了所有必要的包而不是系统方面的python？

我无法发表评论，但我会发布作为答案，尽管我不确定这会解决你的问题。

您确定 Django 安装在您的 venv 上吗？ 如果 django 没有出现在您可能需要安装的列表中，请尝试pip list或pip3 list （取决于系统）。

如果您使用的是 pycharm，您可以使用可视化界面来修改您的 venv， 请参见此处
