问题描述
由于我使用了Electron forge webpack plugin，当我执行npm start时，会在编译预加载脚本步骤后导致错误。它说错误出在Inside Forge。
我查了一下，这是文件观察器 api 中的错误，mainCompilation.fileSystemInfo 未定义，因此无法读取 prop createSnapShot 函数。
我应该如何解决此错误并启动我的应用程序？

√ Checking your system
√ Locating Application
You have set packagerConfig.ignore,the Electron Forge webpack plugin normally sets this automatically.
Your packaged app may be larger than expected if you dont ignore everything other than the '.webpack' folder
√ Preparing native dependencies
√ Compiling Main Process Code
√ Launch Dev Servers
√ Compiling Preload Scripts
An unhandled rejection has occurred inside Forge:

解决：我重新启动项目。也许我错过了一些依赖项。我是从模板复制的，所以应该会按预期发生错误。
