1.pip3安装mysqlclient报错python setup.py egg_info Check the logs for full command output.
在CentOS上部署Django项目时，经常需要安装MySQL数据库引擎，如mysqlclient，在执行pip3 install mysqlclient命令时，可能会报错如下：
ERROR: Command errored out with exit status 1:

----------------------------------------
ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.这是因为缺少mysql-devel包，需要现进行安装，同时为了解决包版本冲突和依赖冲突，需要先下载并安装mysql的yum源，命令如下：
# 下载对应版本mysql的yum源的rpm包
wget http://repo.mysql.com/mysql57-community-release-el7-8.noarch.rpm
# 安装rpm包
rpm -ivh mysql57-community-release-el7-8.noarch.rpm然后再执行yum install mysql-devel命令安装mysql-devel包，打印如下：
Loaded plugins: fastestmirror
mysql-connectors-community | 2.6 kB 00:00:00
mysql-tools-community | 2.6 kB 00:00:00
mysql57-community | 2.6 kB 00:00:00
Loading mirror speeds from cached hostfile
Resolving Dependencies
--> Running transaction check
---> Package mysql-community-devel.x86_64 0:5.7.32-1.el7 will be installed
--> Finished Dependency Resolution
就将mysql-devel包安装成功了。
最后再执行pip3 install mysqlclient命令就可以成功安装mysqlclient引擎。
