Why delete linux version package on version 0.1.8

[zerfew]

When 2018 year ,I were setup ubuntu16.04+python2.7+pyqt5 environment,
I found 0.1.10 version only support windows, but 0.1.8 version support windows and linux both.
so I install pyqt5 on ubunut16.04 used this cmd:
pip install python-qt5==0.1.8
Now 2021 year, when I want setup a new ubuntu16.04+python2.7+pyqt5 environment,
I alse used the same command,installed pyqt5 0.1.8 ,but pyqt5 librarys cannot be imported.
I check /usr/local/lib/python2.7/dist-packages/PyQt5 folder, find the library files were all replaced by windows dll and exe files.
Who can tell me who did this?Why do that?
