Mac系统 python2.7中安装MySQLdb

由于要在python2.7上使用到MySQLdb连接数据库，所以要安装MySQLdb，也就是MySQL-Python。安装之前已经有人告诉我，这个东西比较难装，果然我也遇到好多问题，在百度找了半天，发现好多大佬写下了遇到坑的经历，按照大佬们的方式，我也没有解决，最后是根据报错解决了。

看到有大佬根据知乎上的问题总结了两条命令，对，我也是按照这两条命令执行的：

1.   brew install mysql-connector-c
2.  pip install mysql-python

安装第一个很顺利，然后接着安装第2项内容，报错如下：

xhdeMacBook-Pro:bin xhong$ pip install MySQL-python

        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

百度了半天，有的说是修改mysql_config文件，按照这篇：https://www.easegamer.com/?p=545；我修改了也没用。修改之后再次安装报错如下：

xhdeMacBook-Pro:bin xhong$ pip install MySQL-python

    Traceback (most recent call last):

      File "<string>", line 1, in <module>

      File "/private/var/folders/v6/wvt9z78x4ksd_5fhltwjygd00000gn/T/pip-install-VOZ85j/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

提示环境问题，之后又尝试将mysql_config这个文件的路径加入环境变量，如下：

#安装MySQL-python需要配置的环境变量
export PATH=${PATH}:/usr/local/Cellar/mysql-connector-c/6.1.11/bin/
export PATH=${PATH}:/usr/local/bin/

结果再次安装还是报错上面的一样，最后实在没法，就仔细看了报错的信息：

 

这个报错信息说的是 /usr/local/bin/这个路径下面的mysql_config文件中有语法错误🙅，那就改吧，把第112行前面的箭头 > 去掉；

再次安装，果然好了 ，费了半天时间安装这个MySQLdb；
