如何修复运行时错误:无法关闭正在运行的事件循环 - Python Discord Bot

问题描述 投票:0回答:3

我正在尝试使用 Python 创建一个 Discord 机器人,但是每当我在这里运行示例代码时:

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')

它返回错误:

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')

  File "C:\Users\User\Anaconda3\lib\site-packages\spyder_kernels\customize\spydercustomize.py", line 703, in runfile
    execfile(filename, namespace)

  File "C:\Users\User\Anaconda3\lib\site-packages\spyder_kernels\customize\spydercustomize.py", line 108, in execfile
    exec(compile(f.read(), filename, 'exec'), namespace)

  File "C:/Users/User/Pictures/rito_bot.py", line 22, in <module>
    client.run('token')

  File "C:\Users\User\Anaconda3\lib\site-packages\discord\client.py", line 595, in run
    _cleanup_loop(loop)

  File "C:\Users\User\Anaconda3\lib\site-packages\discord\client.py", line 97, in _cleanup_loop
    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 

其他每一行似乎都运行得很好,但如果没有最后一行,它就无法连接到服务器,这使得它毫无用处。

注意:我已经看到了问题here,但是OP的解决方案似乎不适用于我的情况。

(这里是 Spyder 维护者)要在我们的控制台中运行异步代码,您首先需要安装 nest_asyncio 包,然后在运行任何代码之前调用它,如其自述文件中所述。

我在尝试在

Jupyter Notebook
上运行 Discord 示例时遇到了同样的问题。转向纯 python 脚本为我解决了这个问题。

也许导入这个,会有帮助。因为它对我有用。

如果你使用jupytet笔记本或google colab你将面临这个错误

导入nest_asyncio

nest_asyncio.apply()
