解决Python 3安装gevent时遇到的gcc编译错误

python3 安装gevent报错 GCC error， 按照网上大哥们的指导把，配套的库全部安装一遍后，问题依然没有解决，但是这个些如果没有安装的还是需要进行下安装：

yum install libevent-devel

yum install python devel

yum install python-gevent   

我的操作系统是centos7.6 于是尝试升级了下pip3到最新版本，然后进行gevent的安装就成功了：

python3 -m pip install –upgrade pip

pip3 install gevent==1.4.0
