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)#測試

[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>>>

有時候，上面的包安裝好了，導入失敗

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、說明

python2中支持?MySQLdb

python3為PyMySQL或

python3中mysqldb不再支持，包括mysql-python是安裝不上的。

轉為Pymysql

命令：

pip3 install PyMySQL

使用及安裝參考鏈接：

3、python3安裝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 安裝?mysqlclient

失敗1

[root@localhost ~]#pip3 install mysqlclient

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

按照網上

更新pip3 和 setuptools

[root@localhost ~]#pip3 install --upgrade setuptools

[root@localhost ~]#python3 -m pip install --upgrade pip

繼續失敗

[root@localhost ~]#pip3 install mysqlclient

Traceback (most recent call last):

File"/usr/bin/pip3", line 16, in sys.exit(main())

TypeError:'module' object is not callable

安裝mysql依賴

yum install mysql-devel gcc gcc-devel python-devel

繼續安裝

[root@localhost ~/mysqlclient-1.4.6]#python3 setup.py install

安裝這個，找不到，

sudo apt-get install libmysqlclient-dev

更新apt源試試

使用pip install mysqlclient命令安裝mysqlclient失敗？

安裝mysqlclient報錯如下

1、下載本地whl，安裝

重裝成功

[root@IP mysqlclient-1.4.6]#python3 setup.py install

或者

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