解决办法
1、卸载nodejs重新安装一遍

  ~# U/ ~7 x  l& |2、设置淘宝镜像 npm config set registry https://registry.npm.taobao.org

% `  t9 G% g2 K8 r% |) g3、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

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。
