pip简介
pip是python的包管理工具。

项目主页：https://pypi.python.org/pypi/pip

下载后安装
下载后解压，通过CMD终端进入解压的目录，然后输入以下命令：

python setup.py install

接下来设置环境变量
将 D:\program\Python\Python36\Scripts 添加至PATH，注意格式并替换你自己的python安装目录。

验证安装

C:\Users\mixh>pip list

e –format=(legacy|columns) (or define a format=(legacy|columns) in your pip.con
f under the [list] section) to disable this warning.
lxml (4.1.1)
pip (9.0.1)
setuptools (28.8.0)

pip设置代理

安装包时设置代理的格式：

pip install –proxy http://username:password@proxyIP:proxyPort sphinx

我所在局域网的代码不用设置密码，故使用如下命令即可：

C:\Users\darkmi>pip install –proxy http://proxy.it.xxx.com:8080 nose
