安装mysql_python的适合遇到mysql_config not found解决方案（mac）
用pip安装MySQL-python时候遇到报错：
------我是分割线------
Complete output from command python setup.py egg_info:
sh: mysql_config: command not found
Traceback (most recent call last):
File "<string>", line 20, in <module>
File "/private/tmp/pip-build-bj2vIy/MySQL-python/setup.py", line 17, in <module>
metadata, options = get_config()
File "setup_posix.py", line 43, in get_config
libs = mysql_config("libs_r")
File "setup_posix.py", line 25, in mysql_config
raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-bj2vIy/MySQL-python
------我是分割线------
一招制敌：
终端输入：sudo ln -s /usr/local/mysql/bin/* /usr/bin
然后再重新pip安装，终端输入:sudo pip install MySQL-python
接下来安装就没有问题了
