前言：在某台Centos服务器上安装mysqlclient时一直报下面的错：

这篇博文就来解决这个“ No matching distribution found for mysqlclient”的问题，并记录下整个过程。

01-在同一服务商的同一机房开一台新的主机

02-卸载掉预装的Python3.6,安装好Python3.9,并建立Pyhon3.9和pip3的软链接

详情请参考 https://blog.csdn.net/wenhao_ir/article/details/134294656

03-安装MySQL开发依赖库mysql-devel

sudo yum install mysql-devel

04-安装mysqlclient

pipmy install mysqlclient

05-原因总结

我觉得之前失败的最大原因是我没有把系统预装的Python3.6卸载掉。
