ModuleNotFoundError: No module named 'pywintypes'

Describe the bug

The 'briefcase run' operation encountered an error：
File "G:\beeware-tutorial\bydkmipwd\build\bydkmipwd\windows\app\src\app\bydkmipwd\MacUtils.py", line 2, in
import wmi

ModuleNotFoundError: No module named 'pywintypes'

Steps to reproduce

MacUtils.py line 2: import wmi
I have performed 'pip install pywin32' and 'pip install wmi' operations.
And I have referenced 'pywin32' and 'wmi' in the pyproject.toml file.

Expected behavior

Now the 'run' operation reports the error mentioned above, but the 'dev' operation can start the project normally. I don't know where the problem lies, and I hope to get some clarification. Thank you.

When new requirements for an app are added in pyproject.toml, the build for the app must be updated. You can either run briefcase update or briefcase run -r.

Thank you for your response, but I have tried both 'briefcase update' and 'briefcase run -r' commands, and neither resolved the issue. Additionally, I attempted to manually delete files under the 'build' directory, but still encountered the same error: ModuleNotFoundError: No module named 'pywintypes'.

Took another look; the pywin32 package comes with a pth file and as such this issue is probably related to #381.

I was assuming pywintypes was a package on PyPI....but it appears it's simply a file named pywintypes.py in your app.

If you want to import another file/module in your project, you can use import <app name>.pywintypes or from . import pywintypes (where <app name> is replaced with the name of your app's package name).
