install issues (Could not build wheels for pyobjc-core, pyobjc-framework-Cocoa)

[joeypiccola]

I am trying to install py3-tts on my mac via python3 -m pip install py3-tts. I am using venv fwiw. I am not sure how to debug the following install errors. I have run python3 -m pip install --upgrade wheel successfully. I am using Python 3.12.3.

Interesting this. I've not found this myself. I'm assuming you have Xcode build tools installed. i.e xcode-select --install

the answer is that full wheels are built for silicon and intel Mac.. But that feels a bit heavy-handed (there are a lot of dependencies on Mac)

I added the PyObjC==9.1.1 in the requirements.txt and the error message doesn't exist anymore.

[Luanruy]

It may be the problem with pyobjc==9.0.1? I can install the 9.1.1version successfully. But the 9.0.1 which is used in py3-tts failed to be installed. Someone has mentioned it to pyobjc.

I added the PyObjC==9.1.1 in the requirements.txt and the error message doesn't exist anymore.

I tryed to change 9.0.1 to 9.1.1, but I recived a segmentation fault. Can you run it properly?🥺

I encountered the same error and tried to fix it for 2 days, but I could not solve it, so I gave it up. T_T
I also tried to use pyttsx3 under python3.6, also failed.
