why does python 3.13 ignore the venv i activated five minutes ago? 🤔

    small Flask-ish API, nothing fancy. I moved it to a new box, created a venv, installed requirements, and hooked it up to gunicorn. instead of a running service I got this traceback:

    PS C:\scripts> python sync_reports.py

    PS C:\scripts> python sync_reports.py
Traceback (most recent call last):
  File "C:\scripts\sync_reports.py", line 3, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'
PS C:\scripts> pip install requests
Requirement already satisfied: requests in c:\users\...\python311\lib\site-packages
PS C:\scripts> python sync_reports.py
ModuleNotFoundError: No module named 'requests'

    The weird part: if I source venv/bin/activate and run it, no error at all, is teh venv only half real?

    Do i need to activate the venv inside teh service somehow? Or copy packages to the system Python? Id rather understand the right way than hack smth together that breaks again next month. im about to throw this thing out the window lol

    oh ive been there lol almost always this is two different interpreetrs. compare them directly:

    which python
python -c "import sys; print(sys.executable)"
python -m pip --version

    Then check what the cron job actually calls. If teh unit or script says /usr/bin/python3, it will never see packages from your venv. point it at /path/to/venv/bin/python explicitly.

    Stop using bare pip. use python -m pip install fastapi with the exact interpreter that runs the app. That way the package lands in the same site-packages that the interpreter searches.

    oof activating a venv only changes PATH in ur interactive shell, services, cron and IDE run configs do not inherit that... for systemd set ExecStart=/opt/app/venv/bin/python app.py (or venv/bin/gunicorn), and for cron use teh full path too.
