安装路径D:\\Program Files\\Python27

python环境安装比较简单，下载python语言环境中的windows版本的msi格式文件，下载后双击安装即可。

在安装时选择添加路径到系统中，则环境变量Path中已经自动添加python安装的路径D:\\Program Files\\Python27

运行cmd，在命令行中测试一下

如上图中所示，通过python命令，之后输出经典的Hello, world!，表示python语言环境已经安装成功了。

使用IDLE可以进行python程序编译了。

setuptools和pip的安装：这个是可以实现后续相关组件的自动安装，但是在windows下需要手动下载相关组件，并通过python 运行setup.py来进行安装。

安装方法为解压缩下载的安装包，进入setuptools目录，打开cmd，运行python setup.py install命令来安装。

## setuptools 28.6.1 ##

setuptools是 Python Enterprise Application Kit（PEAK）的一个副项目，它是一组Python的 distutilsde工具的增强工具（适用于 Python 2.3.5 以上的版本，64 位平台则适用于 Python 2.4 以上的版本），可以让程序员更方便的创建和发布 Python 包，特别是那些对其它包具有依赖性的状况。

下载地址：[https://pypi.python.org/pypi/setuptools][https_pypi.python.org_pypi_setuptools]

![1053243-20161029112819171-1156388169.png][]

安装方法为打开cmd，进入setuptools的解压目录D:\\python64\\setuptools-28.6.1，运行python setup.py install命令来安装。

安装完成后可以进入python的安装目录下查看Scripts目录中是否有easy\_install.exe，有则表示安装成功了。然后将Scripts路径也加入到环境变量中。

（注：setuptools 安装完后，下图中是没有后三项的， pip相关内容是pip安装后才出现的）

## pip ##

下载最新版pip，使用python setup.py install指令安装。

## pip 8.1.2 ##

下载地址：https://pypi.python.org/pypi/pip\#downloads

解压缩文件夹，找到setup.py ，进入cmd，使用python setup.py install指令安装。

可以不安装，输入pip指令输出如下：（这条没有尝试成功）
