使用pip安装第三方插件

1. 下载Settools和pip，并安装

a. 下载地址：

setuptools : https://pypi.python.org/pypi/setuptools#downloads pip: https://pypi.python.org/pypi/pip/#downloads
b. 安装方法：

在命令行中进入上面两个工具的解压目录，并执行python setup.py install 来安装两个工具

2. 安装第三方工具，以selenium为例

pip 命令格式：



>>pip list 可以查看已经安装的插件



>>pip show numpy 可以查看插件的信息



>>pip install selenium [version number] 不加版本号就安装最新的release，加版本号可以指定安装哪个版本的selenium。

下面就是安装selenium的过程，最后显示Successfully installed

D:\>pip install selenium
