Please read carefully: this is not about installing packages with Blender's python, but rather ther reverse - ignoring system packages.

When I try to install packages with the pip I installed under Blender, I get messages such as

Requirement already satisfied: svgpathtools in /home/simone/.local/lib/python3.10/site-packages (1.6.1)

however Blender's python then doesn't find them when executing scripts.

How do I get Blender's pip to ignore system python's site_packages?

Right now I am working around this by renaming site_packages, but that's horrible and time consuming.

BTW, this seems new to Blender 3.4 (but no guarantee about that).

This is the command I use:

simone$ /home/simone/blender/blender-3.4.1-linux-x64/3.4/python/bin/pip install scikit-learn

and this the output I get:

Requirement already satisfied: scikit-learn in /home/simone/.local/lib/python3.10/site-packages (1.2.1)
Requirement already satisfied: numpy>=1.17.3 in /home/simone/.local/lib/python3.10/site-packages (from scikit-learn) (1.23.5)
Requirement already satisfied: scipy>=1.3.2 in /home/simone/.local/lib/python3.10/site-packages (from scikit-learn) (1.11.1)
Requirement already satisfied: joblib>=1.1.1 in /home/simone/.local/lib/python3.10/site-packages (from scikit-learn) (1.2.0)
Requirement already satisfied: threadpoolctl>=2.0.0 in /home/simone/.local/lib/python3.10/site-packages (from scikit-learn) (3.1.0)

and the same results come if I use

simone$ /home/simone/blender/blender-3.4.1-linux-x64/3.4/python/bin/python3.10 -m pip install scikit-learn

and this is the screenshot of my preferences:

with no trace of extra/strange paths being added in.

I've also recursively looked for the string site-packages in my .config/blender directory and found nothing suspicious - except in dream-textures.

I think it is an installing issue, not a force-ignore issue.

When you run the pip install with Blender's bundled pip, it still attempts to install the packages in your system's default python folder. You should tell pip where they'll be installed- specifically, Blender's Python's site-packages folder.

Your command will look something like this:

/home/simone/blender/blender-3.4.1-linux-x64/3.4/python/bin/pip install scikit-learn --target=/home/simone/blender/blender-3.4.1-linux-x64/3.4/python/lib/python3.10/site-packages
