CentOS7使用pip安裝mysql-python出錯解決方案

具體錯誤：

[root@localhost liuyuantao]# pip install mysql-python
Collecting mysql-python

    EnvironmentError: mysql_config not found
    
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-7Pn8K6/mysql-python/

上面的錯誤是因爲缺乏mysql_config文件致使，查看下mysql_config文件是否存在

[root@localhost liuyuantao]# find / -name mysql_config
find: ‘/proc/5155’: No such file or directory
find: ‘/run/user/1000/gvfs’: Permission denied

果真mysql_config沒有找到，是由於缺乏mysql-devel，致使mysql_config丟失，安裝mysql-devel便可。

yum install mysql-devel

若提示錯誤應該是MySQL的源存在問題，安裝MySQL的源便可，具體見CentOS7編譯安裝MySQL5.7以後安裝mysql-devel出錯解決方案

mysql-devel安裝成功以後，查看mysql_config是否存在

[root@localhost liuyuantao]# find / -name mysql_config
find: ‘/run/user/1000/gvfs’: Permission denied
/usr/bin/mysql_config

在/usr/bin/mysql_config已經存在，使用pip安裝mysql-python便可

root@localhost liuyuantao]# pip install mysql-python

接下來咱們就能夠使用python操做MySQL數據庫了
