ModuleNotFoundError：沒有名為“django.core”的模塊

Question

我想創建 django 項目，所以我配置了 virtualenv，我安裝了 django pipenv install django==4.0.1當我使用這個命令python3 manage.py startapp Accounts創建應用程序時，我收到了這個錯誤。

(env) zakaria@ZAKARIA:/mnt/c/Users/ZAKARIA/Desktop/project$ python manage.py startapp Accounts
Traceback (most recent call last):
  File "manage.py", line 11, in main
    from django.core.management import execute_from_command_line
ModuleNotFoundError: No module named 'django.core'

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

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    main()
  File "manage.py", line 13, in main
    raise ImportError(
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?

任何人都可以幫助解決這個問題嗎？

Answer 1

而不是python3 manage.py startapp Accounts試試python manage.py startapp Accounts激活你的venv 。

為了解釋為什么這很重要，讓我們 go 通過一個練習。 從沒有激活venv開始，嘗試這個過程（如果你在venv中，你可能需要使用deactivate命令來關閉：

python -m venv my_venv
# The following line assumes you're on Linux or Mac; it appears you're using WSL-2, which is fine
. my_venv/bin/activate
# The following command should show the path to the Python binary in your venv
which python
# The following command may show that you're not hitting the Python version in your venv, but somewhere else
which python3

您要確保使用的是 venv 中的venv二進制文件。 祝你好運！

當我將 Django 與 Docker 連接時，我遇到了同樣的問題。我通過運行以下命令解決了這個問題：

docker-compose 創建--構建
