NotADirectoryError: [Errno 20] Not a directory

[qiangshui]

After executing python setup.py py2app, when I run ./dist/main.app/Contents/MacOS/main, I got this error :

NotADirectoryError: [Errno 20] Not a directory: '/Users/wj/myproject/client/dist/main.app/Contents/Resources/lib/python39.zip/playwright/driver/playwright.sh'

python39.zip is a compressed file， I find a related log in the build output:
copying file build/bdist.macosx-10.9-x86_64/python3.9-standalone/app/python39.zip -> /Users/wj/myproject/client/dist/main.app/Contents/Resources/lib

It's running normally if I got the app file by python setup.py py2app -A .

system version: macOS Monterey 12.6
python: 3.9
py2app: 0.28.4

setup.py:

from setuptools import setup

APP = ['main.py']
DATA_FILES = []
OPTIONS = {}

setup(
    app=APP,
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],
)

Use OPTIONS = { "packages": ["playwright"] }, this will make sure that the "playwright" python package is kept outside of the zipfile.

BTW. Is "playwright" the PyPI package of the same name? If it is I can add a recipe to py2app that will do this automaticly.

Thanks for your replying. Yes, it's the same name.

After I use OPTIONS = { "packages": ["playwright"] }, I got an anothor error:

[ronaldoussoren]

I get one step further with these options:

OPTIONS={
   "packages": ["playwright"],
   "excludes": ["playwright._impl.__pyinstaller.hook-playwright.sync_api", "playwright._impl.__pyinstaller.hook-playwright.async_api"]
}

That does not result in a completely working app bundle though: playwright complains it cannot locate the browser engine. Playwright outside of the app bundle installs those in a folder in ~/Library/Caches, but bundled in an app it looks for the inside the playwright package itself.

It might be possible to work around this problem manually by copying the browser engines manually after running pyapp, e.g. copy the contents of ~/Library/Caches/ms-playwright to main.app/Contents/Resources/lib/python3.9/playwright/driver/package/.local-browsers. That said, I tried this an this also causes problems (I get a traceback ending with the exception playwright._impl._api_types.Error: Target closed).

It seems that the playwright package has some assumptions about its runtime environment that aren't try in a bundles application. That's usually something that I can fix with a recipe in py2app, but researching that takes some time, and I don't have the time to do that research today.

To be continued...
