PyObjC comes presintalled with the Python bundled in macOS. For a stand-alone Python installation you have to install it separately. You can also use QT5 in macOS


You have to install Linux dependencies manually. You can choose between GTK and QT.

PyGObject is used with GTK. To install dependencies on Ubuntu for both Python 3 and 2

sudo apt install python-gi python-gi-cairo python3-gi python3-gi-cairo gir1.2-gtk-3.0 gir1.2-webkit2-4.0

For other distributions, consult the PyGObject documentation

PyQt5 is used with QT. pywebview supports both QtWebChannel (newer and preferred) and QtWebKit implementations. Use QtWebChannel, unless it is not available on your system.

To install QtWebChannel on Debian-based systems.

sudo apt install python3-pyqt5 python3-pyqt5.qtwebengine python3-pyqt5.qtwebchannel python-pyqt5 python-pyqt5.qtwebengine python-pyqt5.qtwebchannel libqt5webkit5-dev

To install QtWebKit.
