用unzip解压缩

1 [根@本地主机请求-2. 18.4 ] # unzip设置工具- 36.5.0.zip

如果在提示符下找不到unzip命令，则可以使用yum进行安装

1 [根@ localhost requests-2.18.4 ] # yuminstallzipunzip

解压缩完成后可以安装

1 [根@ localhost requests-2.18.4 ] # CD设置工具- 36.5.0

2 [根@ localhost setup tools-36.5.0 ] # python setup.py install

Error: Nothing to do

[ root @ localhost requests-2.18.4 ] #

以下原因是系统找不到mysql依赖软件包： 在这种情况下，可以自行安装依赖关系，使其依赖于mysql或mariadb

安装mariadb的dev软件包

1 [ root @ localhost MySQL-python-1.2.5 ] # yuminstallmariadb-develmariadb-embedded-devel

重新安装MySQL-python-1.2.5

[ root @ localhost MySQL-python-1.2.5 ] # python setup.py install

再次报告错误

重新安装python-devel

1 [ root @ localhost MySQL-python-1.2.5 ] # yuminstallpython-devel

再试一次

1 [ root @ localhost MySQL-python-1.2.5 ] # python setup.py install
