7 years ago If I use "brew link --overwrite python" will I need to worry about not being able to use Numpy, OpenCV, or anything of the sort? And could that fix the problem?
Also, I'm not 100% clear on what to do with "export PYTHONPATH=brew --prefix/lib/python2.7/site-packages:$PYTHONPATH." When I entered back into "~/.bash_profile" via ''nano", I saw NO changes? What am I not catching?

7 years ago (I'm assuming python2) If you type this in the terminal
export PYTHONPATH=`brew --prefix`/lib/python2.7/site-packages:$PYTHONPATH
echo $PYTHONPATHyou should see that the brew directory has been added to PYTHONPATH. In another window, go to that site-packages directory and confirm there's a freenect module there. Then
idle
>>> import freenectIf that doesn't work, I'll have to track down a Mac and try it myself.

7 years ago D'oh, I didn't realize that the Formula doesn't build any python bits. This manual way worked for me.
brew install cython
git clone https://github.com/OpenKinect/libfreenect
cd libfreenect
mkdir build
cd build
cmake .. -DBUILD_PYTHON2=ON -DCYTHON_EXECUTABLE="/usr/local/opt/cython/bin/cython"
make
cd wrappers/python/python2
python
>>> import freenectThe permanent solution will be to patch the Formula to take an optional dependency on python and cython.

7 years ago So how does one "patch the Formula to take an optional dependency on python and cython" for the permanent fix?

7 years ago I'm trying to do that at homebrew-core#16772, but there are some remaining issues with the build process.

5 years ago @piedar Hi piedar,
Do you happen to have a solution for python 3.7?
I pretty much followed the instructions on the readme and I'm stuck on the step where i type python setup.py install in the libfreenect/wrappers/python directory. I have no where else to look for help...

4 years ago Any idea how to fix this when using virtualenv? Openfreenect compiles fine--I can view the C++ demos just fine. And I also have the latest Cython in my virtualenv.
seanngpack

4 years ago Okay, I think I fixed the issue. I had to follow the errors and go into freenect.c and change each call to exc_value, exc_traceback, exc_type -> curexc_value, curexc_traceback, curexc_type.

I did the same but still after running python3 -c'import freenect' I have ModuleNotFoundError: No module named 'freenect'. I feel hopeless also I am beginner so many things are new for me.

Can someone give me a hand here?
Installing libfreenect using homebrew work fine for me using:
brew install libfreenect
but apparently, it comes with no wrappers?
Trying to import freenect from python does not work as well...
Running /opt/homebrew/Cellar/libfreenect/0.6.4/bin/freenect-glview works fine for me.
Where do I go from here for importing the lib in python?

@matheusft I suggest you try the steps mentioned as well and see what happens.
Ok, so I ran thru "brew install libfreenect, " as instructed in the ReadMe. But when I go to import it, IDLE keeps giving me this message:
