我想把我的react应用和electron 8打包。我已经按照本文中的说明进行了必要的更改,以适应我的代码:

这是我目前看到的 Package 后。

这是我的包.json

基本上,这是我运行脚本来打包整个东西的顺序。
1.构建
1.建立电子
1.电子组件
如果你能帮忙的话,我将不胜感激。谢谢你,谢谢

我知道我来晚了,但我花了几天时间追踪这个问题。
我首先运行npm run build来打包我的react应用程序,这样我就有了一个构建文件夹。
在我的例子中,在使用electron-forge打包我的应用程序后,在index.html中,我所有的本地导入到我的.js文件中的“/static/js/etc.js”之前都缺少了“.”。
示例:x1c 0d1x
示例2:

一旦将其更改为正确的,如图所示,它加载的一切都很好:

我真的希望这对某人有帮助。

我建议您将当前路由记录到控制台,这样您就可以看到在打开开发和生产构建时加载了哪些页面。
这可能是由路由器引起的。在您的项目中,您可能只有一个真实的的HTML页面-index.html,因此请确保它加载的是/index.html而不是/index.html/#(哈希模式)或其他内容。
同时尝试在main进程中添加此事件侦听器:

// Replace YOUR_WINDOW and modify the line that loads the URL 
// (the same way you load URL when the window is created)
YOUR_WINDOW.webContents.on('did-fail-load', () => {
  if (process.env.NODE_ENV === 'production') {
    YOUR_WINDOW.loadURL('app://./index.html')
  }
})

我也遇到了同样的问题,我发现问题是在build/index.html中外部资源没有链接好:

<script defer="defer" src="/static/js/main.4acc3563.js"></script>

而不是:

<script defer="defer" src="./static/js/main.4acc3563.js"></script>

您可以注意到缺少'.'
我找到的解决方案是将以下内容添加到package.json

...

"homepage": "./",

...

之后,我重建了应用程序,确保重新运行甚至React重建命令,它的工作!
