在 azure 函数中导入自定义模块时出现 ModuleNotFound

Question

我使用 vscocde azure 函数模板创建了一个项目。我想导入一个脚本来运行该函数。但是将我的 mymodule.py 文件与 __init__.py 放在同一目录并使用 import mymodule 后，我收到以下错误

> Executing task: . .venv/bin/activate && func host start <

Found Python version 3.8.2 (python3).

您需要注意的两件事：

首先，如果mymodule是可以通过pip安装的公共模块，那么你应该把它放在requirements.txt中，然后你就可以得到它。

其次，如果mymodule是自己创建的模块，那么就是python相对导入问题。您需要使文件夹可以访问。

如果还是不行，请出示你的代码的导入部分和你的函数应用结构的截图。
