On installation of opencv using brew

I installed pyenv and a version of python on it, but executing "brew info opencv" keeps telling me that I don't satisfy dependencies such as python.

I searched on the internet to see if there is a way to avoid installing python on real(as opposed to virtual) environment included in "brew install opencv", but in vain.

I found an option for brew install opencv though, but the latest opencv seems to have deprecated all these, as "brew info opencv" does not produce "==> Options" comments.

We cannot help installing python, python@2, numpy etc even if pyenv is installed??

In my environment
/usr/local/Cellar/opencv/3.4.5/lib/python3.7/site-packages/cv2/
