javascript - prerender-spa-plugin 在服务器上不工作

Question

我正在尝试在服务器上运行构建。但是使用预渲染，会出现以下错误。在桌面版的ubuntu和macOS上，没有这个问题，只是服务器端的问题。我在不同的服务器上试过。

95% emittingError: Failed to launch chrome!

我在 webpack 中的 prerender-spa-plugin 设置:

new PrerenderSPAPlugin({
    // Required - The path to the webpack-outputted app to prerender.
    staticDir: _.outputPath,
    // Required - Routes to render.
    routes: ['/', '/abouts', '/mobile-apps', '/docs/service-fees', '/news', '/legal/Terms%20of%20use', '/legal/Refund%20policy', '/legal/Privacy%20Policy', '/legal/Notification%20o$
    renderer: new PrerenderSPAPlugin.PuppeteerRenderer({
      renderAfterDocumentEvent: 'render-event',
      headless: false,
    }),
  })

我有同样的问题，它在本地完美运行，但问题出现在服务器上。我的临时修复是减少在

routes: []

上传递的路由数量
