导入discord.py时出现TypeError

Question

我刚刚安装了discord.py重写分支，但是尝试使用import discord或from discord.ext import commands只会导致TypeError。

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/site-packages/discord/__init__.py", line 20, in <module>

  File "/usr/local/lib/python3.6/site-packages/aiohttp/http_parser.py", line 15, in <module>
    from .http_writer import HttpVersion, HttpVersion10
  File "/usr/local/lib/python3.6/site-packages/aiohttp/http_writer.py", line 304, in <module>
    class URL(yarl.URL):
  File "/usr/local/lib/python3.6/site-packages/yarl/__init__.py", line 232, in __init_subclass__
    "is forbidden".format(cls))
TypeError: Inheritance a class <class 'aiohttp.http_writer.URL'> from URL is forbidden

虽然错误在技术上来自于yarl而不是来自discord.py本身，但只有在尝试导入模块时才会出现错误。

我已经尝试重新安装python以及discord.py重写分支，如果它在RPi 3 B +上运行有任何区别

Answer 1

您的aiohttp包可能已过期。

尝试

pip install --upgrade aiohttp

Answer 2

我试图在我的python 3.7上安装discord.py并且它不起作用。

我不得不安装python 3.6.6以使其工作，也许你正在使用python 3.7，如果是这样你应该尝试回滚到python 3.6.6
