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

所以我最近尝试通过cmd安装discord.py，但是无论我是否使用pip3 py pip，它都会给我一个错误.它说我需要安装Visual Studio 14，但我已经安装了Visual Studio 16.

So I recently have tried to install discord.py through cmd but its giving me an error no matter if I use pip3 py pip. It says i need to install visual studio 14 but i have visual studio 16 installed.

我已经卸载并重新安装了python 3.9.0，我已经通过"pip install --upgrade pip"进行了更新.仍然会给我同样的错误.

I've uninstalled and reinstalled python 3.9.0 i've updated through 'pip install --upgrade pip" and it still gives me the same error.

这是错误:

推荐答案

有两个(如果使用语音，则三个)discord.py的依赖项尚未针对Python 3.9.0预先构建好轮子，必须从源代码进行编译.您有三个选择.

Two (three if using voice) of discord.py's dependencies do not yet have prebuilt wheels for Python 3.9.0 and must be compiled from source. You have three choices.

  1. 安装Micosoft Visual C ++独立编译器( https://wiki.python.org/moin/WindowsCompilers )，然后尝试在没有声音的情况下安装discord.py(PyNaCl在Windows上仍然有问题).

  1. Install the Micosoft Visual C++ standalone compilers (https://wiki.python.org/moin/WindowsCompilers), and try to install discord.py without voice (PyNaCl still has issues on windows).

1a)或者，您可以安装从https://www.lfd.uci.edu/~gohlke/pythonlibs/.请注意，此处未提供PyNaCl.

1a) Alternatively, you can Install these two wheels (yarl, multidict) precompiled from https://www.lfd.uci.edu/~gohlke/pythonlibs/. Note that PyNaCl is not supplied here.

降级到Python 3.8.6，它确实为所有discord.py的依赖项预先构建了轮子.

Downgrade to Python 3.8.6 which does have prebuilt wheels for all of discord.py's dependencies.

这篇关于Python:Discord.py错误:无法为使用PEP 517且无法直接安装的multidict，yarl构建轮子的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
