- m3 F  M- ?3 a- n解决办法
1、卸载nodejs重新安装一遍
' b5 k6 f2 x" r7 Z: H( I, {
5 r) o+ m# w2 f6 p8 T8 J% w2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org
; u* n0 Z# r! b/ [0 G, {
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
: r2 j5 c8 w9 c4 V' ?* Y/ a- I
  o# C% M& j/ K9 _1 U) B5 B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。

  L# `1 h3 B" [& o+ o: p7 S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！
