Question

我试图用Python创建Discord机器人，但是每当我在此处运行示例代码时：

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

    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

其他所有行似乎都可以正常运行，但是如果没有最后一行，它就不会连接到服务器，这使它毫无用处。

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。

Answer 1

（此处为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程序包，然后按照其自述文件中的说明运行任何代码之前先对其进行调用。

Answer 2

我在尝试在Jupyter Notebook上运行Discord示例时遇到了相同的问题。转向普通的python脚本为我解决了此问题。
