第一次使用Stack Overflow，所以如果它的格式很糟糕，我们深表歉意。
几个月前，我决定结合 discord.py 模块启动一个网络抓取项目，在 Dance Dance Revolution 中生成一组 3 首随机歌曲，用户可以在 Discord 上请求。歌曲名称和夹克图片是从一个名为remywiki的节奏游戏相关网站中抓取的。不久前，编程运行良好。但是，每当我尝试启动启动 Discord 机器人的.py文件时，我现在都会收到此错误：

我相信我的错误来自错误使用 BS 的某个地方，但我无法弄清楚我到底在哪里搞砸了。此外，我使用 grequest 来帮助加快从网站上解析所有歌曲标题的速度，因为非异步执行此操作需要很长时间。
这是使用BS的代码的一部分。 SO不建议上传我的全部代码，但可以根据要求提供更多代码。

任何帮助或建议将不胜感激。谢谢！
在导入 grequests 之前，您是否将请求导入到其他地方？
这可能是由于 grequests/gevent 的已知问题造成的。
