TypeError: Inheritance a class from URL is forbidden

Question

我运行在尝试运行我为 Discord 制作的机器人时遇到了这个错误。这是在下载一些模块后发生的。有什么办法可以解决这个问题吗？

Answer 1

Discord.py rewrite 分支最近在 requirements.txt 和 aiohttp 支持方面有一些问题。需要手动安装低版本的yarl来支持discord.py需要的aiohttp库

您需要运行以下内容：

pip install "yarl<1.2"

更新

新版本discord.pyrewrite修复了该问题，不再需要按照上述解决方法进行操作。正确的做法是从 GitHub 重新下载 discord.py rewrite 并升级软件包。

Answer 2

我运行遇到了同样的问题，但为了设置 self-bot，只需将其粘贴到 requirments.txt:

yarl<1.2

Answer 3

此答案适用于 aiohttp。如果有人使用 aiohttp 2.2.5 遇到这个问题，可以使用 0.13.0 版本的 yarl 修复它。例如：

pip install yarl==0.13.0
