解决pip安装mysqlclient报错error C1083: Cannot open include file: ‘mysql.h‘: No such file or directory
问题描述：
系统：win10(64位)
python版本：3.7.8
MySQL Server 8.0
MySQL Connector C 6.1
使用pip install -r requirements.txt 命令时，安装到mysqlclient时报错（mysqlclient已通过pip命令安装完成）：

报错截图如下：
原因解析：
对于64位Windows，pip安装mysqlclient时，它只在Program files (x86)文件夹中搜索了某些MySQL文件(例如" mysql.h" )，而不会搜索Program files，本机将MySQL连接器安装到了C:\Program Files\MySQL中，而在C:\Program Files (x86)中没有MySQL安装目录，所以在Program files (x86)中未找到任何内容，导致错误。
解决方法：
将C:\Program Files\MySQL\MySQL Connector C 6.1文件夹拷贝到C:\Program Files (x86)\MySQL\MySQL Connector C 6.1目录中（本人采用了非常简单粗暴的办法，拷贝了整个MySQL文件夹），重新执行命令pip install -r requirements.txt。命令执行成功

E:\HttpRunnerManager>其他原因：
原因一：
1、Mysqlclient版本不匹配，Mysqlclient下载地址https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient
2、Mysqlclient安装命令
pip install mysqlclient-1.4.6-cp37-cp37m-win_amd64.whl
3、验证是否安装成功，使用命令：
python
>>> import MySQLdb
无报错即为成功

>>>原因二：
没有安装MySQL Connector-c，下载地址https://downloads.mysql.com/archives/c-c/，下载安装即可。
原因三：
使用pip install mysql-connector命令安装mysql-connector
