Python Discord.py-ctx是必需的参数

Question

我试图制造一个不和谐的机器人，我正在遵循一个简单的教程，任何我不能得到最简单的命令来工作。 我在Python3.6上运行discord.py版本0.16.12

    #Imports
import time
import discord
import asyncio
from discord.ext import commands

#Initialize
client = discord.Client()#Creates Client
bot = commands.Bot(command_prefix='!')#Sets prefix for commands(!Command)

#Code
@bot.command()
async def SendMessage(ctx):
    await ctx.send('Hello')

代码应该可以工作，但是它给了我一个错误discord.ext.commands.errors.MissingRequiredArgument: ctx is a required argument that is missing.

Answer 1

从documentation：

A command must always have at least one parameter, ctx, which is the Context as the first one.
