Same problem here using Windows 10 and TypeScript. Someone has a workaround, plz?

UPDATE: By setting custom configuration options in vue.config.js like explained here the plugin actually works, exept it generates an app.html file (from the main App component, I beleve) which does not include prerendered <meta> tags that are correctly injected into index.html. Maybe this could be avoided in vue.config.js..? Also, I'm missing .prerender-spa.json in the root directory of the project (which maybe wasn't generated because of this issue) and I have no idea what registry: undefined is used for.

My current setup:

pluginOptions: {
  lintStyleOnBuild: true,
  stylelint: {},

  prerenderSpa: {
    registry: undefined,
    renderRoutes: [
      '/',
      '/about'
    ],
    useRenderEvent: false,
    onlyProduction: true,

    headless: true,
    customRendererConfig: {
      args: ['--auto-open-devtools-for-tabs']
    }
  }
},
