解决ModuleNotFoundError: No module named ‘dlib‘

代码

import dlib

报错

ModuleNotFoundError: No module named 'dlib'

操作

pip install dlib

报错

DEPRECATION: Could not build wheels for dlib which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.
