I am trying to install PyQt5 on my Mac but I do not know how to use it well. I have tried to install sip doing
cd ~/Downloads/sip-4.17 python configure.py
In ~/.pip/pip.log I discovered:
~/.pip/pip.log
Skipping https://pypi.python.org/packages/... (from https://pypi.python.org/simple/pyqt5/) because it is not compatible with this Python
Simply installed newwer version of Python 3 from official website and pip3 install PyQt5 finally worked.
pip3 install PyQt5
