尝试导入 QtCore 时出现此错误

from PyQt5 import QtCore 
 
Traceback (most recent call last): 
  File "<stdin>", line 1, in <module> 
ImportError: dlopen(/usr/local/lib/python2.7/site-packages/PyQt5/QtCore.so, 2): Symbol not found: _PyBytes_FromString 
Referenced from: /usr/local/lib/python2.7/site-packages/PyQt5/QtCore.so 
Expected in: flat namespace 
     in /usr/local/lib/python2.7/site-packages/PyQt5/QtCore.so

请您参考如下方法:

您可以通过更新 PyQt5 来解决此问题 (instructions here, although they're currently temporarily offline)和 pyqt_tools(你可以用 pip 来做)。
