Hello, I noticed that during an update with pamac, it didn’t use the first entry of python path available and the update failed because in the python environement pamac chosed, I didn’t have the build module :

/home/nleconte/miniforge3/bin/python: No module named build
==> ERROR: A failure occurred in build().
Aborting...
Instead of choosing the default and first entry (/usr/bin/python), it selected the last one (/home/nleconte/miniforge3/bin/python) which did not have the build module, so the update failed.
In my current environment, I didn’t activate any particular python environment, so I expect pamac to choose the first one and not the last one :
whereis python
python: /usr/bin/python /home/nleconte/miniforge3/bin/python /usr/share/man/man1/python.1.gz
The command I used to make the update was : pamac update -a
I tried the following : PYTHONPATH=/usr/bin/python pamac update -a
I finally tried this to avoid letting pamac handle the elevation to root and to avoid losing the value I manually provided for PYTHONPATH : sudo PYTHONPATH=/usr/bin/python pamac update -a
I think somehow, it could be handled better by pamac. Just use the first path (=default one) in the python path instead of the last one.
What you are trying to do is not valid maintenance and is unsupported.
Pamac uses libalpm and it is not designed to update in user path.
If you are using python packages you should maintain using pip in a virtual environment.
I repeat Pamac is designed to update system packages.
Even given the fact that you can somehow trick pamac into installing into your home - using sudo will effectively wreck permissions inside your home.

Hello @linux-aarhus that’s exactly my point.
I’m NOT trying to use a virtual environment, and I am purely updating system packages (python-pyrsistent), but pamac tries to use a virtual environment during the build of this system package whereas it should not, and should rather use the python from the system itself.
I had to “trick” pamac because of this undesired behavior.

python-pyrsistent
This is a custom buildscript from AUR.
If this misbehaves - it is matter for the maintainer - or it is your local configuration - please check your environment variables.
That said - I tested the build and - pamac build as expected on my workstation.

Ok, thank you.
It seems linked to my env somehow, as when I simply type python, it is not using the good one. I had to run the following to disable the “undesired behavior” that was caused by conda :
conda config --set auto_activate_base false
