[PyQt] pyqtdeploy-build fails for iOS app

I am attempting to update a project to pyqtdeploy 2.0.  I have the sysroot
setup, but when attempting to build my application I get an import error
for PyQt5.QtCore.  PyQt5 is setup and runs my app perfectly, and pyqtdeploy
itself runs perfectly.  Below is the actual error.  Any ideas on what I did

Note that I am using a pyenv virtual environment (pyenv virtualenv) if that
is relevant .....

*Compile OS:*  MacOS High Sierra (10.13.4)

Examining the python environment used by the file "builder.py" referenced
in the traceback, I get the following information:

*sys.executable*: /usr/local/var/pyenv/versions/3.6.5/bin/python
*sys.path*: ['/usr/local/var/pyenv/versions/3.6.5/bin',

This looks wrong in two ways, though perhaps I am simply either doing
something wrong or misunderstanding what it should look like:

   1. I am using a pyenv virtual environment (pyenv virtualenv).  As such,
   the correct executable path should be whatever is setup by my pyenv


   It appears that pyqtdeploy-build is taking the real executable and
   ignoring the virtual environment, which breaks pyenv functionality.  (which
   is possibly acceptable in this situation except for the fact that I can't
   actually compile the iOS application).

   2. The python module path (sys.path) is missing the pyenv virtual
   environment site packages which should be found here:


   It appears that pyqtdeploy-build is looking for PyQt5 in the sysroot
   directory (/Users/morrisde/contract/PiranhaColorQt10/ios/sysroot_test/
   lib/python3.6/site-packages), however no PyQt5 installation exists in
   that location.

Can anyone help with how to setup an iOS build environment?
Is it possible to use pyenv (with or without a virtual environment)?
Or is there some other setup which must be used?
Or am I missing a build step?

I attached my sysroot.json config file in the previous email.  Here are the
build commands I am using (with full python virtualenv setup):

brew install pyenv pyenv-virtualenv
pyenv install 3.6.5
pyenv virtualenv -p python3.6 3.6.5 piranha-qt5
pyenv local piranha-qt5
pip install sip==4.19.8 pyqt5==5.10.1

pyqtdeploy-sysroot --sysroot ${HOME}/contract/PiranhaColorQt10/ios/sysroot_test
                   --source-dir ${HOME}/contract/pkgsrc sysroot.json \
                   --target ios-64

pyqtdeploy-build --build-dir
                 --target ios-64 \
                 --sysroot ${HOME}/contract/PiranhaColorQt10/ios/sysroot_test

Any help on what I am doing wrong?

Thank you,
