为什么我会收到错误“该命令已经是一个现有的命令或别名”，而它不应该是？

Question

我只是试着制作Discord机器人，我试着把这个命令放到一个类别中，但是，不管我怎么称呼这个命令，这个错误都会出现。 这是我的密码：

import discord,random
from discord.ext import commands 

bot = commands.Bot(command_prefix=';')

@bot.event
async def on_ready():
    print("bot is ready for stuff")
    await bot.change_presence(activity=discord.Game(name=";help"))

class general_stuff(commands.Cog):
    """Stuff that's not important to the bot per say"""

    @bot.command()
    async def lkibashfjiabfiapbfaipb(self, message):
        await message.send("test received.")

bot.add_cog(general_stuff())
bot.run("TOKEN")

这就是我得到的错误：

The command lkibashfjiabfiapbfaipb is already an existing command or alias.

无论我对命令做了多少更改，它都会不断给出相同的错误

你在正确的轨道上。出现错误的原因是，当你启动程序时，它从顶部读取，然后向下运行

class general_stuff(commands.Cog):
    """Stuff that's not important to the bot per se"""

    @bot.command() # Command is already registered here
    async def lkibashfjiabfiapbf(self, message):
        await message.send("test received.")

bot.add_cog(general_stuff()) 
# It tries to load the class general_stuff, but gets the error because
# it's trying to load the same command as it loaded before

@bot.command将方法添加到bot并加载它。使用Cogs，您可以使用@commands.command()进行操作。它只将方法转换为命令，但不将其加载

您的代码应该如下所示

...
class general_stuff(commands.Cog):
    """Stuff that's not important to the bot per se"""

    @commands.command()
    async def lkibashfjiabfiapbf(self, message):
        await message.send("test received.")
...
