解决办法
  P6 d% M" t7 g; y+ w1 L1、卸载nodejs重新安装一遍

, @1 I2 E6 t1 U8 h! ~# \, z  D2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org

0 A. |5 f1 v. J( {1 A" T3、安装nodejs所需的环境（Visual Studio XX、python什么鬼的）,执行这个命令会自动检测并帮你安装好，npm install --g --production windows-build-tools

4、关键所在！！！执行编译时指定python版本，npm install --python=python2.7

由于我的电脑之前安装过python3版本，并且设置了环境变量，所以npm install会找我默认的python,所以执行时指定nodejs只支持的python2版本。

然后，神奇的事情到了，我把编译包modules删掉后重新编译(这次不指定python2版本直接npm install)，居然奇迹般的又没有报错！！！想不通。。。难道npm会将上次编译成功的配置保存下来？？算了不纠结了哭泣！
