诗不升级polars 15.16

Question

我有一个主要由 python 和 polars 代码组成的存储库。 每次我想用诗歌更新或添加库时，我都会收到此错误。 在版本 15.15 之前，我对 polars 没有任何问题。 我尝试在 IDE (PyCharm) 中更新 Polars，也尝试使用 Brew。 它与最新的 polars 版本有关还是在系统 (Mac M1) 方面？ 不幸的是，我现在一无所获。 有人能帮我吗？

Answer 1

我pip install polars==0.15.16然后它起作用了。 我希望它会在未来得到修复，但这作为一种解决方法很好。

Answer 2

polars不为您的平台提供wheel 。 所以它必须从sdist文件构建。 这失败了，因为：

Cargo, the Rust package manager, is not installed or is not on PATH.
        This package requires Rust and Cargo to compile extensions. Install it through
        the system's package manager or via https://rustup.rs/
