Which webview to use in Python3?

Question

linux

I am using virtualenv for a Python3 project . When I install the library in my project with pip install pywebview[qt] , the env folder is 350MB. The file was specified by the interpreter #! ./env/bin/python3 , still some file is missing:

qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Аварийная остановка (стек памяти сброшен на диск)

You need some kind of library to view the web page, but without Qt - it's too heavy.
js support is also required.
