PySide2.QtWidgets.QxxxxLayout.addWidget 使用错误的参数类型调用

Question

我正在尝试使用 addWidget 函数将 FigureCanvasQTAgg 参数作为小部件添加到某些布局，但出现了 TypeError。只有在尝试运行我使用 pyinstaller 构建的独立应用程序时才会出现此错误。当运行直接使用脚本时一切正常。

我正在使用 python=3.6、PySide2=5.12.3、pyInstaller=3.4

from PySide2.QtWidgets import QApplication, QMainWindow, QMessageBox, QLineEdit, QComboBox, QWidget
import matplotlib
matplotlib.use("Qt5Agg")
from PySide2.QtCore import Qt
from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt5agg import NavigationToolbar2QT as NavigationToolbar
from matplotlib.figure import Figure

class TasksConfigCreatorAdapter(QMainWindow):
    def __init__(self):
        super(TasksConfigCreatorAdapter, self).__init__()
        self.dialog = Ui_TasksConfigCreatorDialog()
        self.dialog.setupUi(self)  
        self.figure = None
        self.setupCanvasLayout()

    def setupCanvasLayout(self):
        if self.figure is None:
            self.figure = plt.figure()
            self.canvas = FigureCanvas(self.figure)
            self.figure.set_facecolor("white")
            self.toolbar = NavigationToolbar(self.canvas, None)
            self.dialog.canvasLayout.addWidget(self.canvas, *(0, 0))
            self.dialog.canvasLayout.addWidget(self.toolbar, *(1, 0))

TypeError: 'PySide2.QtWidgets.QGridLayout.addWidget' called with wrong argument types:
  PySide2.QtWidgets.QGridLayout.addWidget(FigureCanvasQTAgg, int, int)
Supported signatures:
  PySide2.QtWidgets.QGridLayout.addWidget(PySide2.QtWidgets.QWidget, int, int, PySide2.QtCore.Qt.Alignment=Default(Qt.Alignment))
  PySide2.QtWidgets.QGridLayout.addWidget(PySide2.QtWidgets.QWidget, int, int, int, int, PySide2.QtCore.Qt.Alignment=Default(Qt.Alignment))
  PySide2.QtWidgets.QGridLayout.addWidget(PySide2.QtWidgets.QWidget)

Answer 1

通过将 PyQt5 模块添加到规范文件中的排除列表来解决此问题。当尝试在一个文件夹模式下创建独立文件时，我发现添加了 PyQt5 个文件以及 PySide2 个文件，这些文件会中断并导致此问题发生。

Answer 2

我遇到了类似的问题。

TypeError: 'qRegisterResourceData' called with wrong argument types:
  qRegisterResourceData(int, str, str, str)
Supported signatures:
  qRegisterResourceData(int, unicode, unicode, unicode)

我的错误是我使用了 Python3 而没有使用 -py3 标志来编译 qrc 文件，默认为 Python2.
