其实我在一个月前就学到这里了，当时就出现这个报错了。我就跳过了，今天我再次回顾我的课程，检查未完成任务时，再次尝试了它。遗憾的是，现在还是出现这个报错。

Please try one of the following steps to move forward.

Click on the “Restart Step” button and force a refresh of your page with CTRL + F5 .

or - Try the step in incognito or private mode.

or - Disable any/all extensions that interface with the freeCodeCamp website (such as Dark Mode, Ad Blockers, or Spellcheckers).

or - Ensure your browser is up-to-date or try a different browser.

I hope one of these will work for you. If they not please write to support@freecodecamp.org
