ERROR: Not opened“_multiarray_umath.cpython-312-darwin.so”(Mac platform)

[fcunnn]

I use Mac+VSCode, and my Python version is 3.12.6，

I ran the example of 'serious-python/src/serious_python/example/run_deample' and it ran very well.
I need to use the Python library akshare (only using this one library), and my requirements. txt looks like this:

//requirements.txt
akshare

---

My Python program looks like this:

//main.py
print("Hello from Python program!")

import akshare as ak
tool_trade_date_hist_sina_df = ak.tool_trade_date_hist_sina()
print(tool_trade_date_hist_sina_df)

Then I generated app.zip and ran the Flutter main program. The screenshot of the error message is as follows:

The error message is roughly as follows: Not opened“_multiarray_umath.cpython-312-darwin.so”, and Apple cannot verify whether “_multiarray_umath.cpython-312-darwin.so” contains malicious software that may endanger Mac security or leak privacy

What should I do? Thank you！！！

This is the same underlying problem as flet-dev/flet#6702: native .so files from Python dependencies aren't code-signed, so macOS security policy blocks them. You hit the quarantine form of it ("Apple cannot verify..."); the hardened-runtime form reports it as "library load disallowed by system policy".

Worth being straight about the current state: serious_python still doesn't sign macOS dependency .so files — macos_utils.dart merges the arm64/x86_64 slices with lipo and leaves it at that. The signing work is happening on the flet build macos side in flet-dev/flet#6702, which signs every bundled Mach-O inside-out with the hardened runtime and notarizes the result. Will suggest you give it a try, once that PR is merged and feature is released.
