},小知识：你安装electron-rebuild之后要把它运动到dependencies中
执行之后报错如下：

就很 "shabi"，我系统的python版本就是2.7.3的（也切换3.7尝试也不行），可是还是报这个错误。
最后解决方案就是修改源码（同时也把python版本指向2.7）
1.编辑器打开这个源码文件
2.修改源码
然后再次运行
.\node_modules\.bin\electron-rebuild.cmd
就搞定了，真 "shabi"。
补充，下面查看npm执行的时候使用的配置
npm config get userconfig
把这里的python设置成python，就会根据你配置的环境变量来使用python版本
