pip install -U PySide error

Question

Does anyone know how to avoid the following error when running pip install -U PySide as per the official website instructions here: https://pypi.python.org/pypi/PySide/#installing-pyside-on-a-mac-os-x-system

Note that I have already done brew install qt successfully.

You are using pip version 7.0.3, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

UPDATE (3-16-2016):

I recently got my hands on a fully updated Mac OS X 10.11 (El Capitan). I proceeded to successfully brew install qt and then tried pip install -U PySide once again (as per these instructions: https://pypi.python.org/pypi/PySide/#installing-pyside-on-a-mac-os-x-system). Unfortunately, I once again received an error:

It's been many months since my original post and judging by the upvotes, I'm not the only one with this problem. As such, I'm starting to suspect that perhaps the instructions to https://pypi.python.org/pypi/PySide/#installing-pyside-on-a-mac-os-x-system are simply outdated. If anyone actually gets this to work, please upload the recipe. Thank you.

Answer 1

As of June 2018 on MacOS High Sierra, you'd still encounter this issue.

• Make sure to install qt 4.8.7, brew install qt would install qt5 by default which is not compatible with PySide, if you did install qt5, uninstall it and then install qt4.

  brew tap cartr/qt4

  brew install qt@4

• Create an alias for qmake in your bashrc, if qmake is not detected alias qmake="/usr/local/Cellar/qt@4/4.8.7_5/bin/qmake"

• pip install pyside should work now, it took around 30 minutes for it to complete. So, be patient.
