Django项目run manage.py不会生成名为Django的模块

Question

我在做一个django项目，作为一个小型个人网站的后端，django内置的localhost服务器运行平稳，直到我在windows 10中意外删除了python的应用程序执行别名（这只是在完成之后发生的，可能不是罪魁祸首）。情况是，当我使用manage.py时，它总是导致名为“django”的模块出现

(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?

我试着解决了一点，但发现终端（venv已经被激活了）在运行时总是连接到系统级python，而python中没有安装django，这让我很困惑。以下是来自venv的python控制台：

(venv) C:\Users\hongl\PycharmProjects\fluentdesign>python

C:\Users\hongl\PycharmProjects\fluentdesign\venv
C:\Users\hongl\PycharmProjects\fluentdesign\venv\lib\site-packages

我只是想知道manage.py的django内置服务器发生了什么，为什么我不能在venv中用python运行它，它安装了所有必要的包，而不是系统级python

我无法发表评论，但我将作为答案发布，尽管我不确定这是否能解决您的问题

您确定您的venv上安装了Django吗？尝试pip list或pip3 list（取决于系统），如果django没有出现在该列表中，您可能需要安装它

如果您使用的是pycharm，则可以使用可视化界面修改您的venvsee here
