So I generated an openapi client using openapi-generator.

And I now want to install it to my zippapp.

There must be something wrong with my overal structure, though.

I have an app folder. It contains my __main__.py file, along with everything else I need.

It’s also where I pip install my dependencies into. (Not sure if that’s the correct way to go about it, but it worked for other dependencies, so …)

So after generating the openapi client, I

OUT_ABSOLUTE="<path to generated openapi client>"
APP="${PWD}/app"

sudo chown -R "${USER}" "${OUT_ABSOLUTE}"

pip install -t "${APP}" "${OUT_ABSOLUTE}" --upgrade

this says it succeeds, with

after which I compose and run my app

python -m zipapp app -o my_app.pyz
chmod +x my_app.pyz

python my_app.pyz

This is where things stop going the way I want them to.

After pip installing the openapi client, my app folder looks like this:

As you can see, the pydantic_core._pydantic_core package is present.

And yet, trying to run the app gets python to complain that

I appreciate the irony of getting a “not found” error on line 404, but I’d rather python finds its stuff.

How do I get this to work?
