what works

obfuscating works for dummy hook like this

print('hook')

pyarmor man

pyarmor man does not work

Please debug hook script ./.pyarmor/hooks/main.py as normal script, make sure it could be compiled by Python interpreter.

[jakkwis]

This script cames from pyarmor documentation

https://pyarmor.readthedocs.io/en/latest/tutorial/customization.html#using-hook-to-check-network-time-by-other-service

Anyway I got same error using below hook. Which works when used as plain script.

import os
from datetime import datetime

directory = "/tmp"

filepath = os.path.join(directory, str(datetime.now().strftime('%Y-%m-%d')))

with open(filepath, 'w') as file:
    pass

print(f"Empty file created: {filepath}")

[jondy]

Reproduced in Python 3.11+, it will be fixed in next release.

Here is pre-release https://pyarmor.dashingsoft.com/downloads/temp/pyarmor-8.5.10.zip

[jondy]

Fixed in 8.5.10
