[PyQt] [Bug] PyQt5.QtWidgets.so: undefined symbol error

[redstone-cold]

I installed PyQt5 from Ubuntu 15.04's software repositories on the development machine ,after using cx_Freeze to freeze my PyQt scripts into executables, then run the executables in another machine with PyQt5 installed from Ubuntu 14.04's software repositories, I got the error 
/PyQt5.QtWidgets.so: undefined symbol: _ZNK14QPlainTextEdit16inputMethodQueryEN2Qt16InputMethodQueryE8QVariant




I noticed that if PyQt5 version is different on different machine ,and  if we run the freezed PyQt application on these machine , we will got this error , hope fix this !
