! J  z( d( j5 I  O1、卸载nodejs重新安装一遍

* l8 ~! C5 S1 t3 |6 l! [2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org
7 F2 I, A5 t  L$ l) Y* A
3、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
6 m% X# R9 d$ B7 Q0 X" b  j
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。

. O5 z: Y( _3 B- H- j- i0 z$ h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！
