我试图在mcc .py中创建一个命令-
@commands.command()
async def mcoc(self, ctx, tier_str:int,*,champname:str):
champname = champname.strip()
champname = champname.lower()
if champname == "bwcv":
champname=="blackwidow_timely"
url = f"https://auntm.ai/champions/{champname}/tier/{tier_str}"
session = AsyncHTMLSession()
r = await session.get(url)
await r.html.render(sleep=1, keep_page=True, scrolldown=1)
information = await r.html.find("div.sc-hiSbYr.XqbgT")
sig = await r.html.find('div.sc-fbNXWD.iFMyOV')
name = await r.html.find('div.sc-cxFLnm.izBVou')
tier_access = information[0]
self.tier = tier_access.text
async with ctx.typing:
embed = discord.Embed(title=f"{self.name_of_champ}",description=f"More Information about {self.name_of_champ} can be found (here)[{self.url_page}]")
await ctx.send(embed=embed)
但是我不断得到错误-
Ignoring exception in on_command_error
Traceback (most recent call last):

raise RuntimeError('This event loop is already running')
RuntimeError: This event loop is already running
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "/home/indo/.local/lib/python3.9/site-packages/discord/ext/commands/core.py", line 94, in wrapped
raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: RuntimeError: This event loop is already running
即使在继续尝试之后，我仍然得到错误，原因是什么，我如何解决这个问题?
解决此错误
pip install nest_asyncio
你可能也需要在你的python应用
import nest_asyncio
nest_asyncio.apply()
