如何在React + Electron应用程序中重新定位目标不明确的构建文件？

标签： javascript node.js reactjs electron electron-builder

我正在尝试使用react＆electronic建立一个桌面应用程序。我可以使用npm start build来构建项目，但是当我运行可执行文件时，会得到一个带有白色屏幕的节点应用程序，因为该应用程序找不到所需的资源。

enter image description here

这些错误是：

Failed to load resource: net::ERR_FILE_NOT_FOUND /F:/static/css/main.056419ee.chunk.css:1   
Failed to load resource: net::ERR_FILE_NOT_FOUND 2.eba76f4b.chunk.js:1  
Failed to load resource: net::ERR_FILE_NOT_FOUND main.175818bb.chunk.js:1

F:是正确的驱动器，但是我不认为Electron应该在驱动器根目录下寻找static目录。我不知道是什么原因造成的，也不知道为什么会有领先的/。另外，我不知道为什么要在不同的目录中查找其他两个块文件。这三个文件都位于./build/static/js/中。

  • 这是我的第一个reactjs应用程序，也是我的第一个nodejs应用程序之一，所以我不确定如何调试它。我在所有的构建步骤上都不是很清楚，因为我使用了一些没有解释任何内容的样板和教程。
  • 我最初开始使用的命令来自create-react-appp，特别是npx create-react-app creative-ontology-editor
  • 当我用npm start和npm run electron-dev运行它时，react部分工作正常。从那里，我尝试使用this tutorial和this package example等使电子工作。
  • 我正在考虑将该项目公开，如果这样做将有助于对其进行故障排除。

源代码

index.html

这是内置电子应用程序显示的html ：（注意：我作了美化，但将缩小的js放在一行中，以便可以轻松看到其余部分）

package.json

这是我项目的package.json。我知道我的开发人员和正常依赖者可能混在一起了，但是我怀疑这是问题的一部分/

答案 0 :(得分：0)

在Kitze's article中，我的package.json中缺少一行：

"homepage": "./"

他甚至解释了它：

  

最后一件事：

     

在package.json中设置“主页”，否则打包的应用程序将找不到.js和.css文件。
