本地 Debian 10 上的 Django Web App 运行 但在 Azure 上失败

Question

我可以 运行 我的网络应用程序在我的本地机器上 - 没有错误。 但是当将目录结构移植到 Azure 时，我得到 ModuleNotFoundError: No module named 'django'.

这是我所做的：

• 我的应用在 GitHub 上公开可用。 虚拟环境中的应用 运行（称为 deploydjango）。 这反映在 repo 的树结构中。
• 我 ensured that Python version 是正确的（在我的本地机器上是 3.8）。
• 我将代码发布到 Azure（使用 Visual Studio 代码的 Azure 扩展）。
• 浏览到 web app URL 时， 我收到错误消息：

:( Application Error
If you are the application administrator, you can access the diagnostic resources.

• 这让我在 Web 应用服务的 Azure 页面上诊断和解决问题。 我在这里找到了可用性和性能。
  • 在这里找到选项卡“Web App Dow”。
    • 根据 Application Logs 我被告知： Application logs from instance: lw0sdlwk00016P contain an error or a warning
    • 点击 More info，我得到一个日志告诉我：

Answer 1

2021-02-18T12:02:07.203377427Z 来自 django.core.wsgi 导入 get_wsgi_application 2021-02-18T12:02:07.203381027Z ModuleNotFoundError：没有名为 'django'

的模块

上面两行表示 Django 没有安装

如果已安装，请检查以下文档：
