解决办法
1、卸载nodejs重新安装一遍
6 l3 C2 K& \: z# \/ Y8 R
! |" z8 v% u5 n( |# m& _0 F2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org

$ M; V8 r1 l( j" c" D3、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
) G7 M# h& i! l/ a8 L
, C7 g/ n% y$ Y3 _% q! X6 |2 }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。
5 S6 Y) J7 y6 d5 ]0 x
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！
