' Z# `  `% {2 s' g2 }4 h. c3 g解决办法
1、卸载nodejs重新安装一遍

2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org

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
" m: F9 t. \6 _( B4 R3 o0 J, h
7 j5 g. h- p( F& p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。
