linux mysql python包_03_mysql-python模块， linux环境下python2，python3的

---恢复内容开始---

1、Python2 正常

[root@IP ~]#pip install mysql-python

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

Requirement already satisfied: mysql-python in /usr/lib64/python2.7/site-packages (1.2.5)#测试

[root@IP ~]#python2

Python 2.7.5 (default, Aug 7 2019, 00:51:29)

[GCC4.8.5 20150623 (Red Hat 4.8.5-39)] on linux2

Type"help", "copyright", "credits" or "license" formore information.>>> importMySQLdb>>>

有时候，上面的包安装好了，导入失败

另外的

[root@IP ~]#pip install mysqlclient

[root@IP~]#pip list

mysqlclient 1.4.6

#成功

[root@IP ~]#python

Python 2.7.5 (default, Aug 7 2019, 00:51:29)

[GCC4.8.5 20150623 (Red Hat 4.8.5-39)] on linux2

Type"help", "copyright", "credits" or "license" formore information.>>> importMySQLdb>>>

2、说明

python2中支持 MySQLdb

python3为PyMySQL或

python3中mysqldb不再支持，包括mysql-python是安装不上的。

转为Pymysql

命令：

pip3 install PyMySQL

使用及安装参考链接：

3、python3安装PyMySQL

[root@IP mysqlclient-1.4.6]#pip3 install PyMySQL

[root@IP mysqlclient-1.4.6]#python3

Python 3.6.8 (default, Apr 25 2019, 21:02:35)

[GCC4.8.5 20150623 (Red Hat 4.8.5-36)] on linux

Type"help", "copyright", "credits" or "license" formore information.>>> import pymysql

4、python3 安装 mysqlclient

失败1

[root@localhost ~]#pip3 install mysqlclient

WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.
