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If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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.

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for safetensors
Failed to build safetensors
ERROR: Could not build wheels for safetensors, which is required to install pyproject.toml-based projects
解决方法：
去官网下载安装rustup.rs - The Rust toolchain installer
下载完rustup-init.exe，运行安装，会出现窗口提示需要预先安装vs，按默认安装即可。等一会vs安装成功。
需要再次手动运行rustup-init.exe，这次就是正式安装了， 都按模型走即可。全部结束就安装成功了。
再去执行pip安装即可。
