类型导入 discord.py 出错

Question

我刚刚安装了 discord.py 重写分支，但尝试使用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>

"is forbidden".format(cls))
TypeError: Inheritance a class <class 'aiohttp.http_writer.URL'> from URL is forbidden

尽管错误在技术上来自 yarl 而不是来自 discord.py 本身，但该错误仅在尝试导入模块时发生。

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

Answer 1

您的 aiohttp 软件包可能已过期。

尝试

pip install --upgrade aiohttp

Answer 2

我试图在我的python 3.7上安装 discord.py，但它不起作用。

我必须安装 python 3.6.6才能让它工作，也许您正在使用 python 3.7，如果是这样，您应该尝试回滚到 python 3.6.6
