（Python：discord.py）错误：无法为使用 PEP 517 且无法直接安装的 multidict、yarl 构建***

Posted 2023-02-23

【中文标题】（Python：discord.py）错误：无法为使用 PEP 517 且无法直接安装的 multidict、yarl 构建***

【英文标题】：(Python: discord.py) ERROR: Could not build wheels for multidict, yarl which use PEP 517 and cannot be installed directly

【发布时间】：2021-02-06 08:38:55

【问题描述】：

尝试使用 pip install 下载 discord.py，在标题中给了我错误消息。 我使用 cmd 和命令 py -m pip install -U discord 安装，该 cmd 也在管理员中运行。 尝试使用 pip、pip3 和 pip3.9，均无效。

我尝试卸载/重新安装/升级（按此顺序）上述库：

点 亚尔 多字典 *** 设置工具

我尝试过的 python 版本（所有版本都使用默认设置下载，没有任何改变）： python-3.9.0-amd64.exe python-3.9.0.exe

我尝试研究***并尝试使用 --no-binary :all: 进行安装，但它在下面给出了相同的错误消息。

在我尝试过的所有迭代中，它产生了完全相同的错误消息，没有任何偏差

请帮忙：

【问题讨论】：

您是否按照错误消息中的说明进行操作？需要 Microsoft Visual C++ 14.0 或更高版本。使用“Microsoft C++ 构建工具”获取它：visualstudio.microsoft.com/visual-cpp-build-tools

跟随它并且它起作用了......我一定没有正确阅读错误消息。谢谢。

Discord.py v1.6 已于今天早些时候发布，修复了此问题

安装 GCC > 用于 debian linux 基础镜像。

【参考方案1】：

我在一个带有 yarl、multidict 依赖项的包中遇到了类似的问题。为了修复它，我刚刚升级了我的 pip：

pip install --upgrade pip
pip install discord

【讨论】：

pip install --upgrade pip 为我解决了一个与不和谐相关的问题！

【参考方案2】：

2021 年 1 月 8 日更新：Discord.py v1.6 已发布，变更日志中包含构建***的依赖项中的一个凸起

下面的旧消息

如果你想留在 3.9：

安装 Devon 的 aiohttp、multidict、yarl 和 PyNaCl (https://github.com/Rapptz/discord.py/issues/5984#issuecomment-727684359) 的个人版本，例如： py -3.9 -m pip install --upgrade discord.py[voice] --extra-index-url https://gorialis.github.io/pip/ 安装 Micosoft Visual C++ 独立编译器 (https://wiki.python.org/moin/WindowsCompilers) 并尝试在本机工具命令提示符中安装 discord.py 从 master 分支 (https://github.com/Rapptz/discord.py#installing) 上的最新开发版本 discord.py 安装，例如： py -3.9 -m pip install --upgrade "discord.py[voice] @ git+git://github.com/Rapptz/discord.py.git" 从 https://www.lfd.uci.edu/~gohlke/pythonlibs/ 上的预编译***安装 multidict 和 yarl（请注意，此处不提供用于语音支持的 PyNaCl） 安装最新版本的discord.py的依赖并安装不依赖的discord.py，例如： py -3.9 -m pip install --upgrade aiohttp pynacl py -3.9 -m pip install --upgrade discord.py --no-dependencies 使用 Python 3.8，其中预构建的***可用于 discord.py v1.5.1 使用的依赖版本 等待 discord.py v1.6.0 发布（2021 年 1 月 8 日发布）

截至 2021 年 1 月 8 日最新

【参考方案3】：

我今天也遇到了同样的问题，因为我下载了 node.js，它把我的 python 8 更新到了 python 9，我不得不重新安装我的所有模块，包括 dpy。

解决办法就是按照它说的去做

error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

https://visualstudio.microsoft.com/visual-cpp-build-tools/

【讨论】：

没有为我解决问题；在得到这个答案之前我已经完成了所有这些，并且继续得到同样的错误。
