第一次运行前端项目
首先node 和 npm 环境就不说了，是肯定准备好了的。
比如 renren-fast-vue 这个开源项目，clone 下来后，就会做 npm install，让它下载 package.json 文件的各个 module。
通常会遇到的问题如下。
1、没有Python的环境
之前没有装过这个 python，而且要求是 2.7 版本 。
自己来安装吧。给Path添加两个环境变量。
C:\Python27
C:\Python27\Scripts
2、node-sass报错
npm ERR! node-sass@4.9.0 postinstall: `node scripts/build.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the node-sass@4.9.0 postinstall script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
解决办法是，先删除 ，再安装 。
npm uninstall node-sass
npm install node-sass
3、windows的编译环境问题
#npm install# MSBUILD : error MSB4132: 无法识别工具版本“2.0”。可用的工具版本为 "4.0"。
解决办法是，自己去下载安装 Visual C++ 2015 Build Tools 这个工具。再去执行 npm install --msvs_version 2015。
这个步骤，做好后，我重启了电脑。
成功的结果
