进入https://www.lfd.uci.edu/~gohlke/pythonlibs/ 下载相应文件
pip install "whl文件下载路径+whl文件名"
输入>>>pip install C:\Users\lzy\PycharmWork\Pillow-7.1.1-cp38-cp38-win_amd64.whl
再次报错：
Pillow-7.1.1-cp38-cp38-win_amd64.whl is not a supported wheel on this platform.
在cmd命令行输入下列语句，查看pip支持的文件版本和名称
输入
>>>import pip._internal.pep425tags
>>>print(pip._internal.pep425tags.get_supported())
得到：
