推荐答案

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。

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

discord.py的新版本重写解决了此问题，您不再需要遵循上述解决方案。正确的操作是从GitHub重新下载discord.py rewrite并升级软件包。

---

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.
