python - TypeError: Inheritance a class from URL is forbidden

问题描述

I run into this error when trying to run a bot I made for Discord. This occurred after downloading some modules. Is there any way to fix this?

Traceback (most recent call last):

解决方案

Discord.py rewrite 分支最近在其 requirements.txt 和 aiohttp 支持方面存在一些问题。您需要手动安装较低版本的 yarl 以支持 discord.py 所需的 aiohttp 库。

您需要运行以下命令：

pip install "yarl<1.2"

更新

新版本的 discord.py rewrite 修复了这个问题，您不再需要按照上述解决方案进行操作。正确的做法是从 GitHub 重新下载 discord.py rewrite 并升级包。
