Package installation via pip error

Python Help

Hello,
I’m trying to install few python packages via pip3, but at most of them I’m geting Errors that I don’t understand. For example:

root@turris:~# pip3 install pyshark

I have python3.6 installed and pip 20.0.2. I already updated setuptools and wheel. Now i get this:

root@turris:~/skripty# python3.6 -m pip install numpy
Collecting numpy
  Using cached numpy-1.18.2.zip (5.4 MB)
  Installing build dependencies ... done
  Getting requirements to build wheel ... done

I’m using TurrisOS (modificated OpenWRT distro). Does anyone know what is wrong? Thanks.

Ok, I fixed the error for Pyshark by this:

opkg update
opkg install python3-lxml
pip3 install pyshark

But I’m still getting another errors when installing e.g. numpy.

root@turris:~# pip3 install numpy
Collecting numpy
  Using cached numpy-1.18.2.zip (5.4 MB)
  Installing build dependencies ... done
  Getting requirements to build wheel ... done
    Preparing wheel metadata ... error
ERROR: Command errored out with exit status 1: /usr/bin/python3 /usr/lib/python3.6/site-packages/pip/_vendor/pep517/_in_process.py prepare_metadata_for_build_wheel /tmp/tmp6bzl_666 Check the logs for full command output.

Or another package and different error:

root@turris:~# pip3 install matplotlib
Collecting matplotlib
  Downloading matplotlib-3.2.1.tar.gz (40.3 MB)
     |████████████████████████████████| 40.3 MB 11.3 MB/s

So the error message suggests to check the logs. Did you do so? If yes, could you share them?
