缺少 1 个必需的位置参数：“ctx”

Question

我试图让我的机器人在用户对消息做出反应后赋予角色，但每次我都遇到同样的错误。我不明白错误是什么意思。有人可以帮忙吗？ 这是代码：

import discord
from discord.ext import commands
from discord import Member
from discord.ext.commands import has_permissions
from discord.ext import tasks


#sets the command prefix
Client = commands.Bot(command_prefix = "!")

#print Nuggie is ready in the console when the bot is activeted
@Client.event
async def on_ready():
    print("Bot is ready")

@Client.event
async def on_ready(ctx):
    myRole = Role.id("Member")
    channel = discord.utils.get(ctx.guild.channels, name=input("What is the name of the channel?  "))
    channel_id = channel.id
    channel = Client.get_channel(channel_id)
    role = discord.utils.get(message.server.roles, name=myRole)
    message = await Client.send_message(channel, "React with the tick to get access to the server!")
    while True:
        reaction = await Client.wait_for_reaction(emoji="✔", message=message)
        await Client.add_roles(reaction.message.author, role)

我得到的错误是：

Ignoring exception in on_ready
Traceback (most recent call last):
  File "C:\Users\me\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\client.py", line 333, in _run_event
    await coro(*args, **kwargs)
TypeError: on_ready() missing 1 required positional argument: 'ctx'

Answer 1

函数on_ready被定义了两次，当第二次定义时，第一次被删除。错误告诉你函数调用需要一个参数传递给它（ctx）

阅读不和谐文档：https://discordpy.readthedocs.io/en/latest/quickstart.html#a-minimal-bot。 on_ready 方法的定义必须不带任何参数。
