Python 3.6 pyinstaller没有Qt绑定

Question

在命令窗口中运行exe时出现此错误

Traceback (most recent call last):
  File "qtpy\__init__.py", line 169, in <module>
ModuleNotFoundError: No module named 'PySide'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "main.py", line 3, in <module>
  File "<frozen importlib._bootstrap>", line 971, in _find_and_load

  File "qtpy\__init__.py", line 175, in <module>
qtpy.PythonQtError: No Qt bindings could be found

我尝试更新重新安装pyinstaller和pyqt 还安装了pyside
