通过pip错误安装Python包

我试图通过pip3安装一些python软件包，但在大多数情况下，我都会遇到一些我不理解的错误。例如：

root@turris:~# pip3 install pyshark
Collecting pyshark

    Running setup.py install for lxml ... error

我已经安装了python3.6和pip20.0.2。我已经更新了设置工具和控制盘。现在我明白了：

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
    Preparing wheel metadata ... error
ERROR: Command errored out with exit status 1: /usr/bin/python3.6 /usr/lib/python3.6/site-packages/pip/_vendor/pep517/_in_process.py prepare_metadata_for_build_wheel /tmp/tmpf_8xl1dr Check the logs for full command output.

我正在使用TurrisOS（修改的OpenWRT发行版）。有人知道怎么回事吗？谢谢

编辑： 好的，我通过以下方式修复了Pyshark包的错误：

opkg update
opkg install python3-lxml
pip3 install pyshark

但我在安装时仍遇到另一个错误，例如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

或另一个包和不同的错误：

root@turris:~# pip3 install matplotlib
