pip install transformers报错_error: failed building wheel for tokenizers

前提：Python 3.6.2        Tensorflow 2.6.0

问题：windows系统下anaconda虚拟环境安装transformers时，报错如下：

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    If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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.
ERROR: Failed building wheel for tokenizers
Failed to build tokenizers
ERROR: Could not build wheels for tokenizers, which is required to install pyproject.toml-based projects
