Python setup_macos.py install error

[simonedgley]

Hi,

I have tried running the command a number of times, however, setup_macos.py always exited with the error:

Preparing metadata (pyproject.toml) ... error

Some libraries have not been installed yet. Please run 'python3 setup_macos.py' again

[Shaynee-MO]

From the error, we can see that the PyQt5 library failed to install.
Please try running the following two commands one by one to install the library. Then run Main.py to see if it works.
pip3 uninstall PyQt5
pip3 install PyQt5

[simonedgley]

I did try doing that first, still had the problem.

Am repeating - have to allow for the cause off 99% of all errors, the user :)

uninstalled okay
installed okay

same problem when running setup_macos.py.

Doesn't the first part of the error message confirm that PyQt5 IS installed?

chatGPT explained what the error was in setup_macos.py

Furthermore, it gave a correctly written version, which I saved in a file.
When run, it installed everything correctly.

Here is the code:

setup_macos2.py

import os, sys

flag = 0

def run(cmd, bit):
global flag
for _ in range(3):
if os.system(f'"{sys.executable}" -m pip {cmd}') == 0:
flag |= bit
return

run("install -U pip setuptools wheel", 0x01)
run('install "PyQt5>=5.15.10"', 0x02)
run("install Pillow", 0x04)
run("install opencv-contrib-python-headless", 0x08)
run("install numpy", 0x10)

print(f"mask={flag:#04x}")
