Question

我正试图在MacOSCatalina10.15和Python3.9上使用我的python代码 我在运行代码时收到以下错误消息：

Traceback (most recent call last):
  File "/Users/alisa/Dropbox/cff/Python/Project/MyScript.py", line 139, in <module>
    from PyQt5 import QtWidgets, uic
ImportError: dlopen(/usr/local/lib/python3.9/site-packages/PyQt5/QtWidgets.abi3.so, 2): Symbol not found: _InitSignatureStrings
