阿里云主机，原本centos内置python 2.7 ，安装了python 3.6
然后因为要使用lxml 解析文档，结果使用

pip3 install lxml 

Collecting lxml

请教各位如何解决？
按照网上说的额

pip3 install wheel  

然而还是没用请教倒是是怎么解决

当然如果直接用pip 那么是python 2.7的
根据这个帖子 centos python安装lxml报错

yum groupinstall development tools
yum install python-devel

发现安装的都是python 2.7的
结果还是报错
