使用 CUDA 安装 JAX 时出现错误“/usr/bin/bash: line 1: realpath: command not found”

如何解决使用 CUDA 安装 JAX 时出现错误“/usr/bin/bash: line 1: realpath: command not found”

我正在尝试在我的 Windows 笔记本电脑上从源代码构建带有 CUDA 的 JAX。我已经安装了 MSYS2。

我正在按照 here

给出的说明进行操作

但是，我无法使用文档中提到的 realpath 安装 pacman -S patch realpath。每当我从 MSYS2 运行 error: target not found: realpath 时，我都会收到错误 pacman -S realpath。

而且我认为这可能是我收到错误的原因。但是，我无法弄清楚如何使用 realpath 安装 pacman，因为我在任何地方都找不到它。

对此的任何帮助表示赞赏。

我在下面给出了完整的错误信息。
