Как исправить проблему установки модуля?

Question

[Викентий]

Пытаюсь установить opencv на Ubuntu 18.04
$ pip install opencv-python
Выдает:

Collecting opencv-python

    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

      File "/tmp/pip-build-2n2lpc17/opencv-python/setup.py", line 9, in <module>
        import skbuild
    ModuleNotFoundError: No module named 'skbuild'
    
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-2n2lpc17/opencv-python/

Понимаю, что проблема в отсутствии модуля skbuild, загружаю его:

много теста

$ pip install skbuild
Collecting skbuild
Exception:

    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://pypi.org/simple/skbuild/

Оказывается теперь skbuild'a нет. И что мне спрашивается делать? может кто сталкивался с таким?
Примечание:

$ python --version
Python 3.6.9
$ pip -V
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)

p.s: cmake и scikit-build установились нормально

[Сергей Тихонов]

cmake - это в том числе и системный пакет (apt install cmake)
