install error

I encountered the following error using "pip3 install PyTrack-NTU" when installing the package on MacBook Air (M1).

any hints how to fix it?

The solution to my problem. Changes made recently by pip caused the problem. So, using "--use-deprecated=backtrack-on-build-failures" to install. For example, pip install PyTrack-NTU --use-deprecated=backtrack-on-build-failures.

Getting an error from this as well: "option --use-deprecated: invalid choice: 'backtrack-on-build-failures' (choose from 'legacy-resolver')

EDIT: Nothing about pip solves this. I was able to install using the "--no-deps" modifier to prevent the dependencies from being installed. I'll report back if I notice any issue with using up-to-date versions of the requirements

Hello,

Im having issues installing even with "--no deps--" modification. the installer is not responding to my version of SciPy which is installed and up to date. I have updated Brew, wheel, pip everything, even downloaded Xcode... I have no clue what to do.

anyone know how to fix this error? " Using legacy 'setup.py install' for numpy, since package 'wheel' is not installed.

I am also getting an install error. Tried creating a new virtual environment, not working.

I am also having the same issue with freetype & png deps.

I'm also getting this error on install. @titoghose, can you please help us?

[titoghose]

Apologies for the very long delay. I've resolved the installation error, so hopefully should be fine now.
