推荐答案

Discord.py rewrite 分支最近在 requirements.txt 和 aiohttp 支持上出现了一些问题.需要手动安装低版本的 yarl 来支持 discord.py 所需的 aiohttp 库.

Discord.py rewrite branch has some problems recently with its requirements.txt and aiohttp support. You need to manually install a lower version of yarl to support discord.py's required aiohttp library.

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.

UPDATE

The new versions of discord.py rewrite fixed this problem, you no longer need to do follow the aforementioned solution. The correct action to take is to re-download discord.py rewrite from GitHub and upgrade the packages.
