python - 安装基于 pyproject.toml 的项目所需的错误 : Could not build wheels for pandas,

Question

我正在尝试通过笔记本电脑上的 pip install pandas 安装 pandas。

环境:

• Windows 11 专业版
• python 3.10.4
• pip 版本 22.0.4

兼容性:

• Officially Python 3.8, 3.9 and 3.10.
• You must have pip>=19.3 to install from PyPI.

C:\Users\PC>pip install pandas

  note: This error originates from a subprocess, and is likely not a problem with pip.

我尝试过的:

• 更新 pip 到 22.1.1
• 安装轮子0.37.1
• 卸载并安装 pip
• 已卸载并安装 python 3.10.4

使用 pandas 1.5.1 仍可重现错误

感谢@ AKX它指出 future 没有也可能不会有 32 位版本的 pandas。 See the discussion on GitHub .

Pandas 不需要 Anaconda 即可工作，但根据输出中的 python310-32，您使用的是 32 位版本的 Python。

Pandas evidently不为 Python 3.10 提供 32 位轮子(尽管它们有用于 Python 3.8 和 Python 3.9 的 win32 轮子)。 (可能有预制 32 位轮子的替代来源，例如 Gohlke's site 。)

换句话说，在该平台上，您需要从源代码安装 Pandas，这可能是一项相当困难的工作，而且无论如何都不能直接在 pip 中完成(正如您通过错误:元数据生成失败)。

如果您的系统能够运行 64 位 Python，您应该切换到它。
