解决办法
1、卸载nodejs重新安装一遍

9 l8 y3 O" Y9 T9 ~% N, Q& F2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org
4 t: A! \3 S0 x7 g
& H) {/ R' ~9 I, D& Q1 q$ C! O3 }9 w& f3、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
# u; u/ `! {: |' s. C9 b6 X
& Z: a* G- v0 M: P! v3 T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！
