问题
I got quite desperate on this, because I cannot install the open source Qt5 after I installed commercial Qt5 on my laptop.
This issue happened like this: My first trial of install Qt5, I chose the commercial license. Then when I tried to install PyQt5, it said my Qt5 license is commercial, not compatible with PyQt5 license. So naturally, as a open source lover, I uninstalled the Qt5. And reinstalled an open source version. But, no matter how many times I tried, PyQt5 says my Qt5 is still commercial license.
Dose anyone encounter the same issue here? And how did you solve it? (I guess my last shot would be install a VM, but I sincerely hope I don't need to do that).

The issues turns out to be PyQt5 is not compatible with the newest Qt 5.5.0 at the moment. Choose a older version of Qt.

A couple of days ago,when I install PyQt5 in osx(10.9.5) the same problem came to me.I install qt-opensource-mac-x64-clang-5.5.0.dmg,and when I install PyQt-gpl-5.5.tar.gz,it said that Qt5 license is commercial, not compatible with PyQt5 license.So i just remove the Qt5.5 by "rm -rf Qt5.5",then i install qt-opensource-mac-x64-clang-5.4.1.dmg,at last everything works Ok.I googled but din't find something useful.maybe pyqt5 din't support the latest Qt5's license,but Qt5 has GPL and LGPL,pyqt5 has GPL,it should worked...ok,just gussing,hope this will helpful
