Is this pip install persistent for app updates?

[imc67]

For a specific script (check via API the mail logs if there is a S3150 Micros$%t bounce) I needed this:

pip3 install --user requests --break-system-packages

Now the script works perfectly and via cron checks every hour the logs and informs via Pushover. However is this specific pip install persistent over app restart / update?

Hello @imc67
You can use venv or uv to create virtual environments.
Here is a quick cheatsheet for venv => https://aaronlelevier.github.io/virtualenv-cheatsheet/
Many prefer uv these days, see => https://github.com/astral-sh/uv

Hello @imc67
Since the --user flag installed packages as a user, when you run this in the LAMP as root, it will install packages into /root/.local/lib/python3.12/site-packages/
And since /root/.local/ is a symbolic link to /root/.local -> /run/root.local /run is not included in the backup.

What you want to do is create a virtual environment with pip in /app/data/ and use that environment.
That will be included in the backup.

Thanks for your feedback! Can you advise on what command to use to create this?
