PyQt4 and scip for python on Mac OS Sierra
-
Hello,
I am currently failing to import PyQt4 and scip into python on my MacBook (OS Sierra), both of which I need to run a different program. I believe this is due to unsuccessful installation of PyQt4; I have already successfully downloaded SIP using homebrew (it tells me, however, that it is not yet 'linked' and I do not know what that means).
Also, I am not sure what scip is - is it something that I need to download separately?
My main problem appears to be executing the function 'python configure-ng.py' to start building PyQt4. This function, along with "configure.py" are in my directory "/Users/devineurons/anaconda/lib/PyQt-mac-gpl-4.11.4." When I set this as my directory in terminal and execute 'python configure-ng.py,' I receive the following error:
//Querying qmake about your Qt installation... Determining the details of your Qt installation... Error: Failed to determine the detail of your Qt installation. Try again using the --verbose flag to see more detail about the problem.After using the --verbose function with the command, I receive the following:

Try again using the --verbose flag to see more detail about the problem.I have also downloaded Qt 4.8.7-4 using anaconda, but I previously had version 5.7. I'm not sure if it worked completely because I still have some folders related to v5.7 in my Qt folder.
I'm not sure where the problem is at (or if I'm missing something in python or another program) because I am very new to this. I hope someone can help!

Hi,
To avoid losing more time, IIRC conda already provides PyQt4 so you don't have to build it yourself.

@SGaist After reading your response, I executed the following in terminal:
conda install -c anaconda pyqt=4.11.4This supposedly "worked"

The module name is PyQt4 case sensitive.
