Question

我正在使用 python-anywhere 制作 Web 应用程序，在尝试为新的 Profile 模型进行迁移时，出现错误:

ModuleNotFoundError: No module named 'DEGNet'

我尝试查看 Settings.py 和其他类似的内容，但没有发现任何可能导致此错误的内容。

同时列出

Python manage.py help

我在帮助消息下方遇到错误，指出，

Note that only Django core commands are listed as settings are not properly configured (error: No module named 'DEGNet').

我的设置文件如下所示:

我的 WebApp 在当前模块中工作正常，但我就是无法让 makemigrations 工作

在您的 manage.py 文件中，更改 pythonanywhere 上的 DEGNet，它将起作用!祝你好运。
