解决办法
1、卸载nodejs重新安装一遍

5 t# M, P' L3 p% |9 B9 q' d$ H2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org
* B4 U/ y- x/ w* k- t! d- W  x% [
3 D" {# T$ C; D2 [% X3、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
! I" O" g. O4 ]3 S/ a
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。

, U9 `* m- V% s/ m* o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！
