I got the following error installing a dependency with pip
:
pip9.exceptions.InstallationError Command "python setup.py egg_info" failed with error code 1 in /tmp/tmpoons7qgkbuild/opencv-python/
Below is the result of running the command pipenv install opencv-python
on a recent linux (5.4.0 x64) system.

pip9.exceptions.InstallationError: Command "python setup.py egg_info" failed with error code 1 in /tmp/tmpoons7qgkbuild/opencv-python/
How to fix the
pip9.exceptions.InstallationError
Make sure the version of your
pip
andsetuptools
is sufficient formanylinux2014 wheels
.A) System Install
B) Virtual Env / Pipenv
Explanation
For me,
python setup.py egg_info
probably failed because of a recent change in python wheels, asmanylinux1 wheels
were replaced bymanylinux2014 wheels
according to open-cv faq.
