' c- x( y7 Z  P解决办法
9 X' y$ C9 \4 C2 y( \0 @+ G1、卸载nodejs重新安装一遍
/ e' U6 U, ?! e* }9 i! |8 j
2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org

( N! b1 H7 G: x4 ^/ c1 ?* T3、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 v8 v- G$ X7 B- e1 K4 E  ~3 v& X7 M5 o
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！
