Finally, I find that by copying everything under /usr/local/lib/python3.5/dist-packages/PyQt5/Qt/resources/ to /usr/local/lib/python3.5/dist-packages/PyQt5/Qt/libexec/ and /usr/local/lib/python3.5/dist-packages/PyQt5/Qt/libexec/qtwebengine_locales/, the program works. (Though it still output some warnings.)
