本文介绍了(Python:discord.py)错误:无法为使用PEP 517且无法直接安装的multidict，yarl构建轮子的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
尝试使用pip install下载discord.py，在标题中显示了错误消息.我使用cmd和命令py -m pip install -U discord安装，该cmd也已在admin中运行.尝试使用pip，pip3和pip3.9，但所有方法都无效.
trying to download discord.py using pip install, gave me the error message in the title. I installed using cmd and the commands py -m pip install -U discord, the cmd was also run in admin. tried using pip, pip3, and pip3.9, all of which didnt work.
我尝试按该顺序卸载/重新安装/升级上述库:
I tried uninstalling/reinstalling/upgrading (in that order) the said libraries:
- 点
- yarl
- multidict
- 方向盘
- setuptools
(所有版本均以默认设置下载，没有任何更改):python-3.9.0-amd64.exepython-3.9.0.exe
versions of python that I tried (in all versions are downloaded with default settings with nothing changed): python-3.9.0-amd64.exe python-3.9.0.exe
我尝试研究轮子，并尝试使用--no-binary:all:进行安装，但是下面给出了相同的错误消息.
I tried researching about wheels and tried installing with --no-binary :all: as well, but it gave the same error message below.
在我尝试过的所有迭代中，它准确无误地输出了相同的错误消息
in all the iterations of what I have tried, it churned out the exact same error message without any deviation

推荐答案
我今天也遇到了同样的问题，因为我下载了node.js，并将python 8更新为python 9，并且我必须重新安装所有模块.包括dpy.
I also had the exact same issue today, since i downloaded node.js and it updated my python 8 to python 9 and i had to reinstall all of my moduels including dpy.
解决方案是按照提示说
错误:需要Microsoft Visual C ++ 14.0或更高版本.使用"Microsoft C ++构建工具"获得它:https://visualstudio.microsoft.com/visual-cpp-build-tools/
