python'NoneType'对象中的音乐不一致机器人错误，没有属性'create_ytdl_player' [英] Error on music discord bot in python 'NoneType' object has no attribute 'create_ytdl_player'

问题描述

每当我运行此代码时:

@client.command(pass_context=True)
async def ranjaplay(ctx, url):
    server = ctx.message.server
    voice_client = client.voice_client_in(server)
    player = await voice_client.create_ytdl_player(url)
    players[server.id] = player
    player.start()     

它返回此错误:

Traceback (most recent call last):
File "C:\Users\Admin\AppData\Local\Programs\Python\Python36-32\lib\site- 
packages\discord\ext\commands\bot.py", line 846, in process_commands

请帮助我解决此问题

推荐答案

该错误告诉我们 client 为None.为什么?让我们看一下文档:

the error tells us that client is None. why? let's look at the docs:

voice_client_in(服务器)

返回与服务器关联的语音客户端.如果找不到语音客户端，则返回None.

Returns the voice client associated with a server. If no voice client is found then None is returned.

简要检查一下cocs，我假设您必须先创建voiceclient(如果尚不存在).可以使用 Client.join_voice_channel 完成.a>.

Checking the cocs briefly, i assume you have to create the voiceclient first, if it doesn't exist yet. this can be done with Client.join_voice_channel.
