It seems like you delete the About.vue manualy.
Try run npm run electron:build to rebuild the vue project.

Hi xland, you are right with "npm run electron:build" the error is not displayed. I don't understand why, in dev mode I use the normal template which is given by the CLI and don't change anything. What do I have to change?

edit: and interessting info, with electron 6.X.X it doesn't display the error, only with electron 7.X.X.

[xland]

This plugin is not ready for electron 7.X.X
see #540 .

The error is thrown by the prefetch script, the actual script is requested fine. In v2 prefetching will be disabled in development with electron v7+, for now set your vue.config.js to:

module.exports = {
  pluginOptions: {
    electronBuilder: {
      chainWebpackRendererProcess: config => {
        if (process.env.NODE_ENV === 'development') {
          config.plugins.delete('prefetch')
        }
      }
    }
  }
}
