解决办法
1、卸载nodejs重新安装一遍
- r8 T4 ]8 R3 W0 V  {9 q
2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org
7 }; c* Q7 A9 h4 l  L* [
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
* O, |. M% I9 f* [% U
4 K& M6 `. ~7 A8 r, F' M- f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。
( |! h' _. m/ V" E& \8 M6 Q, t  }
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！
