在使用嵌入式 python 发行版运行 Django 应用程序时出现 ModuleNotFoundError 但它在 Windows 中与 python 安装程序版本一起工作正常

Question

我正在尝试在 Windows 中运行 Django 应用程序。

案例A：（带有python Windows可嵌入包）

1. 下载的 python Windows 可嵌入包（64 位）
2. 通过执行

   python -m pip install Django

安装Django
3. 通过运行

   django-admin startproject testDjango1

创建了一个 Django 应用程序
4. 在命令行中执行：

   python manage.py runserver

5. 获取错误：

D:\program_files\python\testDjango1>python manage.py runserver

ModuleNotFoundError: No module named 'testDjango1'

案例 B：（使用 python Windows 安装程序）

1. 下载的 Windows 安装程序（64 位）
2. 通过执行

   py -m pip install Django

安装Django
3. 通过执行

   django-admin startproject testDjango1

创建了一个 Django 应用程序
4. 在命令行中执行：

   py manage.py runserver

5. 应用程序运行良好。

我是否缺少任何设置（如路径设置等）？ 请帮助。

Answer 1

错误消息表明存在 ModuleNotFoundError 并且找不到名为“testDjango1”的模块。这可能意味着目录“testDjango1”不存在或存在但缺少必要的文件和模块。

要解决此问题，您可以尝试以下步骤：

1. 如果您使用虚拟环境，请激活虚拟环境。
2. 确保已安装所有必要的依赖项和模块。您可以通过在命令提示符下运行“pip freeze”来检查这一点。
