音乐bot discord.py的命令

当我尝试运行leave和play命令时，出现此错误。 很长时间以来，我一直在寻找一些问题，但是在任何地方都找不到该错误该如何解决？

警告！所有代码和错误已在CET的17/11/2020 03.24更新。如果您想在写之前检查写的内容

加入和离开代码：

@client.command()
async def join(ctx):
    v_channel = ctx.message.author.voice.channel
    print(v_channel)
    if v_channel:
        await v_channel.connect()

@client.command()
async def leave(ctx):
    player = ctx.message.guild.voice_client
    print(player)
    if player is not None:
        await player.disconnect()

我放print ()来看看我身上发生了什么。当我离开时，Join起作用（实际上它找到通道并进入），它给了我变量，但首先它给了我一个错误。然后出现一个超时错误，该错误会自动使漫游器退出呼叫，但这并不重要。

The above exception was the direct cause of the following exception:

代码on_voice_state_update：

@client.event
async def on_voice_state_update(member, prev, cur):
    print(member)
    print(prev)
    print(cur)
    if prev.channel is not None and client.user in prev.channel.members and len([m for m in prev.channel.members if not m.bot]) == 0:
        channel = discord.utils.get(client.voice_clients, channel=prev.channel)
        print(channel)
        await channel.disconnect()

我对上面的命令做了同样的事情。错误如下：

请不要在该函数中不允许输入任何值

async def on_voice_state_update(member, prev, cur):
    if client.user in prev.channel.members and len([m for m in prev.channel.members if not m.bot]) == 0:
        channel = discord.utils.get(client.voice_clients, channel=prev.channel)
        if channel:
            await channel.disconnect()

@client.command()
async def join(ctx):
    v_channel = ctx.message.author.voice.channel
    if v_channel:
        await v_channel.connect()

@client.command()
async def leave(ctx):
    player = ctx.message.guild.voice_client
    if player:
        await player.disconnect()

编辑：只需更新所有依赖项即可。

grid_forget的成员变量import tkinter as tk class App(tk.Tk): def __init__(self): super().__init__() self.title("Testing") self.minsize(800, 600) self.swap_btn = tk.Button(self, text='swap canvas', command=self.swap_canvas) self.swap_btn.pack() self.canvas1 = tk.Canvas(self, bg="black") self.canvas2 = tk.Canvas(self, bg="blue") self.canvasses = [self.canvas2, self.canvas1] self.current_canvas = self.canvas1 self.current_canvas.pack(expand=True, fill=tk.BOTH) self.draw_some_stuff() def swap_canvas(self): self.current_canvas.pack_forget() self.current_canvas = self.canvasses.pop(0) self.canvasses.append(self.current_canvas) self.current_canvas.pack(expand=True, fill=tk.BOTH) def draw_some_stuff(self): self.canvas1.create_oval(200, 200, 300, 300, fill='blue') self.canvas2.create_rectangle(200, 200, 300, 300, fill='black') self.canvas1.create_oval(400, 200, 500, 300, fill='blue') self.canvas2.create_rectangle(400, 200, 500, 300, fill='black') window = App() #Declaring the window window.mainloop() 的类型为channel。它告诉您回溯中的错误。以某种方式，您需要确保prev中的None设置为非channel的值，或者至少要进行检查。

这是一个简单的检查：

prev

docs描述了为什么None将是@client.event async def on_voice_state_update(member, prev, cur): if prev.channel is not None and client.user in prev.channel.members and len([m for m in prev.channel.members if not m.bot]) == 0: channel = discord.utils.get(client.voice_clients, channel=prev.channel) await channel.disconnect() 。

变量channel的类型为None。它告诉您回溯中的错误。某种程度上，您需要确保player的值不是None，或者至少要进行检查。

player

docs描述了为什么None将是@client.command() async def leave(ctx): player = ctx.message.guild.voice_client if player is not None: await player.disconnect() 。

player的套接字错误可能是相同的问题。它失败了，也许是因为没有东西要留下了。
