运行我的 discord.py 机器人时在 client.run('token') 收到运行时错误

问题描述

我正在尝试用 Python 制作一个 Discord 机器人，它根据您所在的班级(在我的学校)为您提供 Discord 服务器上的角色.我刚刚开始，但每当我尝试运行它时都会收到错误消息(我在 Python 3 Notebook 中的 Google Colab 中运行它).这是我的代码:

I am attempting to make a Discord bot in Python that gives you a role on a Discord server based upon what class you are in (at my school). I have just started, but I am receiving an error whenever I attempt to run it (I run it in Google Colab in a Python 3 Notebook). Here is my code:

from datetime import date
import time
import discord

client = discord.Client()

@client.event
async def on_ready():
    print('We have logged in as {0.user}'.format(client))

client.run('my token (not shown for obvious reasons)')

starttime=time.time()
while True:
  currentTime = time.strftime("%H:%M")
  print("new minute")
  if 0 <= date(int(time.strftime("%Y")), int(time.strftime("%m")), int(time.strftime("%d"))).weekday() <= 4:
    if currentTime == "13:41":
      print("First hour has started!")
    elif currentTime == "13:45":
      print("First hour has started! (hs)")
    elif currentTime == "14:30":
      print("First hour has ended at high school.")
  time.sleep(60.0 - ((time.time() - starttime) % 60.0))

当我运行它时，它会提示我这个错误:

When I run it, it presents me with this error:

---------------------------------------------------------------------------

    378 
    379     def _asyncgen_finalizer_hook(self, agen):

RuntimeError: Event loop is closed

如果我将 client.run 命令放在底部，程序永远不会到达它，因为循环会阻止它到达命令.

If I put the client.run command at the bottom, the program never reaches it because the loop prevents it from reaching the command.

我错过了什么吗?我不知道问题出在哪里.非常感谢帮助.

Am I missing something? I do not know where the problem is. Would appreciate help.

推荐答案

基本上，如果你想在 google colab 上运行 discord 机器人，你需要做各种黑客攻击.这里我使用 discord.ext python 库，执行这个，但是会阻塞，并阻止你执行任何其他单元格.

Basically there are various hacks you need to do if you want to run a discord bot on google colab. Here I use discord.ext python library, executing this, however will be blocking, and prevent you from executing any other cells.

!pip install discord.py
import nest_asyncio
nest_asyncio.apply()
 
import asyncio
await = lambda x: asyncio.get_event_loop().run_until_complete(x)
async def init(what, token):
    await what(token)
import discord
from discord.ext import commands
bot = commands.Bot(command_prefix="")
async def start():
    await bot.wait_until_ready()
    print("ready")
    await bot.get_channel(channelID).send("hi")

bot.loop.create_task(start())

TOKEN = ""   #@param {type: "string"}
