pip安装mysql-python出现的问题

使用 pip 安装 mysql-python 这个包，总是会遇到各种问题，以我个人为例，就在 deepin linux，MacOSX，rhel6.7 上遇到过三次，这里主要针对的是 EnvironmentError: mysql_config not found 问题，解决方案来自于stackoverflow。

Debian/Ubuntu
sudo apt-get install libmysqlclient-dev
新版本（比如2018）的 Debian/Ubuntu
sudo apt install default-libmysqlclient-dev
Mac OSX
export PATH=$PATH:/usr/local/mysql/bin
前提是已经安装 mysql
brew install mysql
Centos/RHEL
yum install -y mysql-devel python-devel python-setuptools
