5 v& W. r- r2 x9 Z# K解决办法
1、卸载nodejs重新安装一遍
' Y0 W$ R0 i) S' ?5 U5 M2 r# |
2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org
" e8 g7 l) h/ b7 |8 |
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
9 ?; e3 x8 C; [8 N/ 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。
5 T0 a; t% Q( R& f; [
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！
