解决办法
" Q0 q$ L" @  ~- Q1、卸载nodejs重新安装一遍

. s8 R" s9 n8 i6 P3 Z) _2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org

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

' Y) E  p/ b/ e; t1 E! Y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。

: ?3 C4 m* E- G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！
