如何在PyQt 5.12.2上启用macOS暗模式？

Question

例如，this page声称PyQt5的最新版本应为我提供macOS Mojave的自动暗模式，而无需改变我的任何东西……除非它没有。

考虑以下简单示例（可以复制粘贴到终端中）：

exec("""\nfrom PyQt5 import QtCore, QtWidgets\n\nclass Ui_MainWindow(object):\n    def setupUi(self, MainWindow):\n        MainWindow.setObjectName("MainWindow")\n        MainWindow.resize(674, 371)\n        self.centralwidget = QtWidgets.QWidget(MainWindow)\n        self.centralwidget.setObjectName("centralwidget")\n        self.gridLayoutWidget = QtWidgets.QWidget(self.centralwidget)\n        self.gridLayoutWidget.setGeometry(QtCore.QRect(50, 10, 601, 281))\n        self.gridLayoutWidget.setObjectName("gridLayoutWidget")\n        self.mpl_layoutBox = QtWidgets.QGridLayout(self.gridLayoutWidget)\n        self.mpl_layoutBox.setContentsMargins(0, 0, 0, 0)\n        self.mpl_layoutBox.setObjectName("mpl_layoutBox")\n        self.pushButton = QtWidgets.QPushButton(self.centralwidget)\n        self.pushButton.setGeometry(QtCore.QRect(280, 300, 113, 32))\n        self.pushButton.setObjectName("pushButton")\n        MainWindow.setCentralWidget(self.centralwidget)\n\n        self.retranslateUi(MainWindow)\n        QtCore.QMetaObject.connectSlotsByName(MainWindow)\n\n    def retranslateUi(self, MainWindow):\n        _translate = QtCore.QCoreApplication.translate\n        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))\n        self.pushButton.setText(_translate("MainWindow", "PushButton"))\n\nif __name__ == "__main__":\n    import sys\n\n    app = QtWidgets.QApplication(sys.argv)\n    MainWindow = QtWidgets.QMainWindow()\n    ui = Ui_MainWindow()\n    ui.setupUi(MainWindow)\n    MainWindow.show()\n    sys.exit(app.exec_())\n""")

我必须怎么做才能启用暗模式？

好的，因此对我而言，尚不明确必须先将其编译为.app，然后再将NSRequiresAquaSystemAppearance添加到顶级Info.plist，但这已解决。
