    import discord

                    current_temperature_celsiuis = str(round(current_temperature - 273.15))
                    current_pressure = y["pressure"]

                    embed.set_footer(text=f"Requested by {ctx.author.name}")
                    await channel.send(embed=embed)








client = MyClient(command_prefix='!')
client.run('my token')

有这样的代码，当你输入命令时!weather New Delhi 给出如下错误

Ignoring exception in on_message
Traceback (most recent call last):
  File "D:\pythonProject16\venv\lib\site-packages\discord\client.py", line 333, in _run_event

    我设法通过从代码中删除类来解决问题。此外，该机器人无法识别该命令，因为它不断分析传入消息中的“hello”内容。在此之前，我必须添加一行来处理命令，以便机器人首先检查消息是否是命令：await bot.process_commands(message)

    最后别忘了替换你的代币！

    现在代码有效:)

    import discord
import requests,json
from discord.ext import commands

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

@bot.event
async def on_ready():
    print('Logged on as', bot.user)

@bot.event  
async def on_message(message):
    # don't respond to ourselves

    if message.author == bot.user:
        return
    
    await bot.process_commands(message)

    if message.content.startswith('hello'):
        await message.channel.send('Hello!')
    
@bot.command()
async def weather(ctx, *, city: str):

    api_key = "7f1e23163b47cbf21184f339f5c8eaf9"
    base_url = "http://api.openweathermap.org/data/2.5/weather?"
        
    city_name = city
    complete_url = base_url + "appid=" + api_key + "&q=" + city_name
    response = requests.get(complete_url)
    x = response.json()

    if x["cod"] != "404":
        async with ctx.typing():
            y = x["main"]
            current_temperature = y["temp"]
            current_temperature_celsiuis = str(round(current_temperature - 273.15))
            current_pressure = y["pressure"]
            current_humidity = y["humidity"]
            z = x["weather"]
            weather_description = z[0]["description"]
            weather_description = z[0]["description"]
            embed = discord.Embed(title=f"Weather in {city_name}",
                                    color=ctx.guild.me.top_role.color,
                                    timestamp=ctx.message.created_at, )
            embed.add_field(name="Descripition", value=f"**{weather_description}**", inline=False)
            embed.add_field(name="Temperature(C)", value=f"**{current_temperature_celsiuis}°C**", inline=False)
            embed.add_field(name="Humidity(%)", value=f"**{current_humidity}%**", inline=False)
            embed.add_field(name="Atmospheric Pressure(hPa)", value=f"**{current_pressure}hPa**", inline=False)
            embed.set_thumbnail(url="https://i.ibb.co/CMrsxdX/weather.png")
            embed.set_footer(text=f"Requested by {ctx.author.name}")
            await ctx.send(embed=embed)

    else:
        print('error')


bot.run('token')
