reactjs - React 应用程序未加载到打包的 Electron 应用程序中

Question

我正在尝试使用 electron 8 打包我的 React 应用程序。我已按照本文中的说明进行了必要的更改以适合我的代码:

https://medium.com/@johndyer24/building-a-production-electron-create-react-app-application-with-shared-code-using-electron-builder-c1f70f0e2649

这是我目前在打包后看到的内容。

这是我的 package.json

基本上这是我运行脚本来打包整个东西的顺序。

1. build
2. 构建 Electron
3. Electron 包

如有任何帮助，我们将不胜感激。谢谢!

Answer 1

我知道我迟到了，但我花了几天时间来追踪这个问题。

我首先运行了 npm run build 来打包我的 React 应用程序，这样我实际上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，我对 .js 文件的所有本地导入都缺少 '.'在“/static/js/etc.js”之前

一旦将其更改为如图所示的正确版本，它就可以很好地加载所有内容:

我真的希望这对某人有帮助。
