我最近将 armbian focus 安装到修补板上，并试图安装 discord python 包。它运行的是预安装的 python 3.8.5 版本，但我只看到当 python 版本为 3.9 时安装不和谐包时出现错误。我还在 windows python 3.8.7 上成功安装了 discord 包，这意味着 windows python 3.8 和 linux python 3.8 之间存在一些我不知道的区别，或者我只是缺少一些包来帮助我安装 discord .py，可能是因为它是预安装的（轻量级）。
我可以看到程序“无法为 multidict 或 yarl 制造轮子”，但我不确定如何解决这个问题。我已经搜索了这个问题的各种版本，但我只发现有人使用 python 3.9，这是一个已知错误。
这是尝试安装的完整输出，错误占了大部分。有没有其他人遇到同样的问题？我想要一些关于如何成功安装 discord.py 的指导。
