Posted 2022-12-03 zhang_xinxiu

     pip是python的包管理工具，pip库中自带了很多python的开源工具包，在使用的时候直接运行pip install就可以下载并安装注册到python模块内，下文将会讨论centos中如何安装pip。

一、安装pip命令

    下载pip安装包：

[root@web1 xxx]# wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz

    解压tar包：

[root@web1 xxx]# tar -vxf setuptools-1.4.2.tar.gz

   进入解压包，并运行安装命令：

[root@web1 xxx]# cd setuptools-1.4.2
[root@web1 xxx]# python2.7 setup.py install

   安装完成后，最后安装pip：

[root@web1 xxx]# easy_install-2.7 pip

   检测是否已经安装成功：

[root@web1 xxx]# pip --version
pip 1.2 from /usr/local/lib/python2.7/site-packages/pip-1.2-py2.7.egg (python 2.7)
