关于Electron升级到4.0+的问题

[JackChius]

electron 升级到相对新的4.0.3后，无法启动项目

开始遇到 app.makeSingleInstance(cb)' is deprecated ，not a function的报错，
查询是方法经过变动，替换为app.requestSingleInstanceLock()后通过，

然后依据提示将component-class/index.js下的
var index = require('indexof');换为
var index = require('component-indexof');

此时CLI显示 webpack: Compiled successfully.，但仍然没有程序窗口弹出

大佬可以帮忙看看吗

• 补充

compile之前行输出的报错，会不会跟这里的类型error有关系？

2.0.0 这个版本确实太旧了，在最新的 win10 1903 上有很多问题，希望能升级一下版本
