TypeError:禁止从URL继承类

Question

在尝试运行我为Discord制作的机器人时遇到此错误.这是在下载一些模块后发生的.有没有什么办法解决这一问题？

Answer 1

Discord.py重写分支最近有一些问题,其requirements.txt和aiohttp支持.您需要手动安装较低版本的yarl以支持discord.py所需的aiohttp库.

您需要运行以下内容:

pip install "yarl<1.2"

UPDATE

新版本的discord.py重写修复了这个问题,您不再需要按照上述解决方案进行操作.要采取的正确措施是从GitHub重新下载discord.py重写并升级软件包.
