提取码：h38g

例：

pip install D:datadlib-19.23.0-cp38-cp38-win_amd64.whl

如报错：

*** is not a supported wheel on this platform

法一：
AMD64

python
import pip._internal
print(pip._internal.pep425tags.get_supported())

win32

python
import pip
print(pip.pep425tags.get_supported())

可能报错

module ‘pip’ has no attribute ‘pep425tags’

法二：

python -m pip debug --verbose

找到支持的标签
例：py38-none-win_amd64

修改文件名字：
例：dlib-19.21.99-py38-none-win_amd64.whl

pip install C:UsersjuerrDesktopdlib-19.21.99-py38-none-win_amd64.whl
