Mac系統 python2.7中安裝MySQLdb

由於要在python2.7上使用到MySQLdb連接數據庫，所以要安裝MySQLdb，也就是MySQL-Python。安裝之前已經有人告訴我，這個東西比較難裝，果然我也遇到好多問題，在百度找了半天，發現好多大佬寫下了遇到坑的經歷，按照大佬們的方式，我也沒有解決，最后是根據報錯解決了。

看到有大佬根據知乎上的問題總結了兩條命令，對，我也是按照這兩條命令執行的：

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

安裝第一個很順利，然后接着安裝第2項內容，報錯如下：

        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，有的說是修改mysql_config文件，按照這篇：https://www.easegamer.com/?p=545；我修改了也沒用。修改之后再次安裝報錯如下：

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

    Complete output from command python setup.py egg_info:
    /usr/local/bin/mysql_config: line 112: syntax error near unexpected token `newline'
    /usr/local/bin/mysql_config: line 112: `> # Create options '
    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

提示環境問題，之后又嘗試將mysql_config這個文件的路徑加入環境變量，如下：

#安裝MySQL-python需要配置的環境變量
export PATH=${PATH}:/usr/local/Cellar/mysql-connector-c/6.1.11/bin/
export PATH=${PATH}:/usr/local/bin/

結果再次安裝還是報錯上面的一樣，最后實在沒法，就仔細看了報錯的信息：

 

這個報錯信息說的是 /usr/local/bin/這個路徑下面的mysql_config文件中有語法錯誤🙅，那就改吧，把第112行前面的箭頭 > 去掉；

再次安裝，果然好了 ，費了半天時間安裝這個MySQLdb；
