[英](Python) Discord bot code returns "RuntimeError: Cannot close a running event loop"
[英]How to Fix Runtime Error: Cannot close a running event loop - Python Discord Bot
我正在嘗試使用 Python 創建一個 Discord 機器人,但是每當我在這里運行示例代碼時:
import discord
client = discord.Client()
@client.event
async def on_message(message):
# we do not want the bot to reply to itself
if message.author == client.user:
return
if message.content.startswith('!hello'):
msg = 'Hello {0.author.mention}'.format(message)
await client.send_message(message.channel, msg)
@client.event
async def on_ready():
print('Logged in as')
print(client.user.name)
print(client.user.id)
print('------')
client.run('tokenhere')
它返回錯誤:
Traceback (most recent call last):
File "<ipython-input-6-ea5a13e5703d>", line 1, in <module>
runfile('C:/Users/User/Pictures/rito_bot.py', wdir='C:/Users/User/Pictures')

client.run('token')

loop.close()
File "C:\Users\User\Anaconda3\lib\asyncio\selector_events.py", line 94, in close
raise RuntimeError("Cannot close a running event loop")
RuntimeError: Cannot close a running event loop
其他每一行似乎都運行得很好,但如果沒有最后一行,它就無法連接到服務器,這使得它毫無用處。
注意:我在這里看到了這個問題,但是 OP 的解決方案似乎不適用於我的情況。
(這里是 Spyder 維護者)要在我們的控制台中運行異步代碼,您首先需要安裝nest_asyncio包,然后在運行任何代碼之前調用它,如自述文件中所述。
我在嘗試在Jupyter Notebook
上運行 Discord 示例時遇到了同樣的問題。 轉向普通的python腳本為我解決了這個問題。
