How to fix the pip9.exceptions.InstallationError Make sure the version of your pip and setuptools is sufficient for manylinux2014 wheels. A) System Install sudo python3 -m pip install -U pip sudo python3 -m pip install -U setuptools B) Virtual Env / Pipenv # Within the venv pip3 install -U pip pip3 install -U setuptools Explanation For me, python setup.py egg_info probably failed because of a recent change in python wheels, as manylinux1 wheels were replaced by manylinux2014 wheels according to open-cv faq.
