我正在尝试编写一个discord音乐机器人程序，它一直有效，直到我将排队系统从URL列表转换为带有歌曲名称的词典，这样我就可以显示接下来播放的内容。
当第二首歌即将播放时，我收到以下错误消息：
C:UserssammyAppDataLocalProgramsPythonPython38libsite-packagesdiscordplayer.py:611: RuntimeWarning: coroutine 'Command.__call__' was never awaited
self.after(error)
RuntimeWarning: Enable tracemalloc to get the object allocation traceback
这是代码，我对它进行了一些修剪，使它不会超长：

ydl_opts = {

'postprocessors': [{
'key': 'FFmpegExtractAudio',

由于您的错误代码声明您忘记添加"；等待"；在第611行的开头。
C:\Users\sammy\AppData\Local\Programs\Python38\lib\site-packages\discord\player.py是脚本的文件路径

我希望这个分解对你有帮助，也有助于你的创业。
