pip install: 無法安裝最新版本的包

在pypi上查看pkg的頁面，因為有些pip包的版本對特定的python版本有要求

pip install error: “Python.h: No such file or directory”

src/kerberos.c:18:10: fatal error: Python.h: No such file or directory
       #include <Python.h>
                ^~~~~~~~~~
      compilation terminated.

Fix

安裝python版本對應的devel包, 比如

$ sudo yum install python38-devel  # for py38
$ sudo dnf install python39-devel  # for py39

pip install error: “ERROR: Can not execute setup.py”

ERROR: Can not execute `setup.py` since setuptools is not available in the build environment.

Fix: pip install -U setuptools
