推荐答案
设法解决该问题，该问题与使用的SIP版本有关.
Managed to sort it out, the issue was related to the used SIP version.
我使用了与PyQt5 5.7兼容的SIP版本，即SIP 4.18.1，并解决了该问题.
I used SIP version compatible with PyQt5 5.7 which is SIP 4.18.1 and the problem was solved.
下一步:
$make
我遇到了另一个问题:
error: 'WindowOkButtonHint' : is not a member of 'Qt'
error: 'WindowCancelButtonHint' : is not a member of 'Qt'
为解决此问题，我编辑了〜/QtCore/sipQtCoreQt.cpp文件，并删除了2条有问题的行.
To solve this I edited the ~/QtCore/sipQtCoreQt.cpp file and removed the 2 problematic lines.
