No module named sip

We have a third-party library that is delivered to us as a WHL file; that library uses this Qt5 module. We are running using Python 2.7. Our application runs beautifully inside PyCharm, but when we create an executable using pyinstaller, the resulting file crashes immediately, leaving this in the terminal window:

Qt: Untested Windows version 10.0 detected!
Traceback (most recent call last):

  File "site-packages\RTL\face.py", line 12, in <module>

    exec(bytecode, module.__dict__)

    module = imp.load_module(fullname, fp, filename, ext_tuple)
ImportError: No module named sip
[28164] Failed to execute script Main

Is there something special that has to be done, either in the creation or the consumption of the WHL file, to get sip to install correctly?

The third party has fixed the issue, not sure how.
