Could not build wheels for nnunet, which is required to install pyproject.toml-based projects

引用[1]:ERROR: Could not build wheels for tokenizers, which is required to install pyproject.toml-based..._JOJO黄金之风的博客-CSDN博客。 引用[2]:经历：安装完OpenCV后在import cv2时报错ImportError: numpy.core.multiarray failed to import， 网上查出方案是numpy版本不适配，我就卸载重新安装了。（pip uninstall如果报错权限不够，就在前面加上sudo）但安装一直报错Could not build wheels for numpy，which is required to install pyproject.toml-based projects （不论是换哪个源都是这样） 。 引用[3]:error: can't find Rust compiler If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler. To update pip, run: pip install --upgrade pip and then retry package installation. If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain. [end of output] note: This error originates from a subprocess, and is likely not a problem with pip.

回答: 这个错误提示表明在安装nnunet时无法构建wheels，而这是安装pyproject.toml-based项目所需的。[1]这个问题可能是由于缺少一些依赖或者环境配置不正确导致的。有几种可能的解决方案可以尝试。首先，你可以尝试更新pip，运行命令pip install --upgrade pip，然后重新尝试安装nnunet。[3]另外，你还可以尝试安装Rust编译器，可以从系统包管理器中安装，确保它在安装过程中的PATH环境变量中。或者，你也可以使用rustup（https://rustup.rs）来下载和更新Rust编译器工具链。[3]此外，你还可以检查是否缺少其他依赖项，例如numpy，如果是的话，可以尝试重新安装它。[2]如果以上方法都没有解决问题，你可以尝试在相关的论坛或社区寻求帮助，以获取更具体的解决方案。
