这是一个来自mysql官方的bug，反正我是看不懂。

Exception: Wrong MySQL configuration: maybe https://bugs.mysql.com/bug.php?id=86971 ? ---------------------------------------- Error: An error occurred while installing mysqlclient!
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/rw/kmt8v6lj2fb37k0kh1ggm4m40000gn/T/pip-install-rwvfazf6/mysqlclient/ This is likely caused by a bug in mysqlclient. Report this to its maintainers.
mysqlclient的作者在源码里已经写了个exception是专门针对这个报错的，就是上面加粗的那一句黑色的链接
Wrong MySQL configuration: maybe https://bugs.mysql.com/bug.php?id=86971 ?
它说，错误的mysql配置，可能是链接里的问题。
这里就不打开链接了解释了，反正就是一个官方的bug，里面也写了怎么解决。
首先安装mysql-connector
brew install mysql-connector-c
然后修改一下mysql_config文件，当然基于安全性的考虑需要先备份一下文件
cp /usr/local/bin/mysql_config /usr/local/bin/mysql_config.backup
然后修改文件
sudo vim /usr/local/bin/mysql_config
找到对应的内容位置
# Create options
libs="-L$pkglibdir"
libs="$libs -l "
修改成
# Create options
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"
这时候安装mysqlclient就没问题了。。
