安装指定版本的transfomers报错ERROR: Failed building wheel for tokenizers

问题：打算安装

transformers == 4.9.1

但是一直报错 

  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

解决方法： 

安装高版本的，能用就行，指定版本的估计是不兼容

pip install --upgrade pip
pip install transformers

安装成功！
