大概意思是在安装gevent时发生错误，找不到Python.h文件
gevent是Python web开发时保证高并发性能的一个工具，导致此错误的原因大概是没有安装python-dev
于是去安装python-dev
直接安装：
sudo yum install python-dev
又报错：
Repository epel is listed more than once in the configuration
Last metadata expiration check: 0:35:25 ago on Fri 14 May 2021 03:39:58 PM CST.
No match for argument: python-dev
Error: Unable to find a match: python-dev
换一种安装方式，
我的是CentOS8.2（支持yum的系统都行），可以采用以下命令先找到包
yum search python | grep -i devel
安装：
yum install python36-devel.x86_64
