可以看到是缺少Python.h文件，进入/lib/pythonx.x目录查看是否缺少该文件

[root@data1 /]# cd /usr/include/python3.6m/
[root@data1 python3.6m]# ls
pyconfig-64.h

没有则安装python-devel（Ubuntu应该安装python-dev）

[root@data1 /]# yum search python | grep devel
Last metadata expiration check: 0:18:02 ago on Mon 06 Jul 2020 02:23:55 AM UTC
....
python36-devel.x86_64 : Libraries and header files needed for Python development
python38-devel.x86_64 : Libraries and header files needed for Python development
...
[root@data1 /]# yum install python36-devel.x86_64

再次安装就可以了

[root@data1 /]# pip3 install pyxattr
