【英文标题】：My cogs file didn't load into my main file (discord.py)

【问题描述】：

当我尝试运行我的 discord 机器人时，cogs 文件似乎不起作用。我什至尝试在 Discord 中使用负载。我已经观看了许多有关 cogs 的视频并阅读了文档，但我找不到任何解决方案。任何人都可以发现错误吗？ 这是我的 cogs 文件

import discord
from discord.ext import commands, tasks
from itertools import cycle


class UpdateCode(commands.Cog) :

  def _init_(self, client) :
    self.client = client

  @ commands.Cogs.listener()

  async def on_ready(self):
    print("We have logged in as 0.user".format(self.client))
    self.status_swap.start()
    self.status = cycle([
      " Unanswered Question of Life", 
    " Self - Referential Paradox", 
    " Near-infinite density?", 
    " Dark matter ?", 
    " Measurement of the speed of light in one straight line", 
    " Schrodinger's cat ???"
    "436c69636b2074686973206c696e6b20666f72206672656520766275636b7320212121212121203a200a68747470733a2f2f7777772e796f75747562652e636f6d2f77617463683f763d6451773477395767586351 (try to decrypt this)",
    "The light side of Discord is the path of many unnatural abilities"
    ])

  @ tasks.loop(minutes = 5)
  async def status_swap(self):
    await self.client.change_presence(activity = discord.Game(next(self.status)))

def setup(client) :
  client.add_cog(UpdateCode(client))

这是我的主文件

import discord
import os
from discord.ext import commands, tasks
from online import keep_alive

client = commands.Bot(command_prefix = "!")

@ client.command()
async def load(ctx,extension) :
  client.load_extension(f"cogs.extension")

@ client.command()
async def unload(ctx,extension) :
  client.unload_extension(f"cogs.extension")

for filename in os.listdir('./cogs') :
  if filename.endswith('.py') :
    client.load_extension(f'cogs.filename[:-3]')

keep_alive()
client.run(os.getenv('MATH_VAR'))

这是错误

Traceback (most recent call last):
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/bot.py", line 606, in _load_from_module_spec
    spec.loader.exec_module(lib)
  File "<frozen importlib._bootstrap_external>", line 848, in exec_module
  File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
  File "/home/runner/Math-Bot/cogs/update.py", line 6, in <module>
    class UpdateCode(commands.Cog) :
  File "/home/runner/Math-Bot/cogs/update.py", line 11, in UpdateCode
    @ commands.Cogs.listener()
AttributeError: module 'discord.ext.commands' has no attribute 'Cogs'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "main.py", line 18, in <module>
    client.load_extension(f'cogs.filename[:-3]')
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/bot.py", line 678, in load_extension
    self._load_from_module_spec(spec, name)
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/bot.py", line 609, in _load_from_module_spec
    raise errors.ExtensionFailed(key, e) from e
discord.ext.commands.errors.ExtensionFailed: Extension 'cogs.update' raised an error: AttributeError: module 'discord.ext.commands' has no attribute 'Cogs'

如果您知道如何解决此错误，请评论我的代码。谢谢。

【参考方案1】：

分析错误

分解第一部分的错误：

Traceback (most recent call last):
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/bot.py", line 606, in _load_from_module_spec
    spec.loader.exec_module(lib)
  File "<frozen importlib._bootstrap_external>", line 848, in exec_module
  File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
  File "/home/runner/Math-Bot/cogs/update.py", line 6, in <module>
    class UpdateCode(commands.Cog) :
  File "/home/runner/Math-Bot/cogs/update.py", line 11, in UpdateCode

    # First hint which points to your code.
    @ commands.Cogs.listener()

# Second hint which points the problem in your code.
AttributeError: module 'discord.ext.commands' has no attribute 'Cogs'

引用现有代码

其次，您可以参考UpdateCode Cog 的定义方式，它是基于command.Cog 而不是command.Cogs。 class UpdateCode(commands.Cog) 注意丢失的's'。

结论

基于我提出的前两点，我们可以得出结论，当您通过在词 'Cog 中包含 's' 来定义 @ commands.Cogs.listener() 装饰器时存在一个小错误'。
