Discord.py点歌排队系统

Question

我正在尝试编写一个 discord 音乐机器人，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字典，以便我可以显示接下来正在播放的内容。

当第二首歌曲即将播放时，我收到此错误消息：

C:\Users\sammy\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\player.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，我对其进行了一些修改，使其不会太长：

global ydl_opts
ydl_opts = {
            'format': 'bestaudio/best',
            'postprocessors': [{
                'key': 'FFmpegExtractAudio',
                'preferredcodec': 'mp3',
                'preferredquality': '192',
            }],
        }


from discord.utils import get
global voice
global queue_list
queue_list = {}

def queue():
    global queue_list
    print("hi")
    print(len(queue_list))
    if len(queue_list) != 0:
        keys = list(queue_list.keys())
        values = list(queue_list.values())
        print("AAAAAAAAAAAAA: " + str(values[0]))
        play_url(str(values[0]))
        print("AAAAAAAAAAAAA2: " + str(queue_list[keys[0]]))

        del queue_list[keys[0]]

Answer 1

(Usually) 表示你忘记在协程（以async开头的函数）之前使用await，这是强制性的。

Answer 2

C:\Users\sammy\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\player.py:611: RuntimeWarning: coroutine 'Command.call' was never awaited self.after(error) RuntimeWarning: Enable tracemalloc to get the object allocation traceback

由于您的错误代码表明您忘记在第 611 行的开头添加“await”。

C:\Users\sammy\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\player.py 是你脚本的文件路径

:611: 是上述文件中的行

运行时警告：从未等待协程 'Command.call' self.after（错误） 是文件中出现的错误。

我希望这个细分对您有所帮助，有助于您的事业。
