我试图在服务器上运行Nightmare.js.我很清楚它在Linux上无头,需要xvfb.我不明白为什么我在DEBUG模式下继续出现以下错误：

  nightmare queuing process start +0ms
  nightmare queueing action "useragent" +3ms
  nightmare queueing action "goto" for https://news.ycombinator.com +2ms
  nightmare queueing action "cookies" +1ms
  nightmare queueing action "goto" for https://news.ycombinator.com/login +0ms

  nightmare queueing action "click" +0ms

  nightmare electron child process exited with code 2: undefined +25ms

这是我的Dockerfile：

RUN npm install

CMD DEBUG=nightmare* xvfb-run --server-args="-screen 0 1024x768x24" node tux.js -s hn -m create -p 11878025

有什么想法吗？非常感谢帮助.
