i think this is an issue with python>=3.11
if you install mecab-python3==1.0.6
it seems to work

Had the same issue. I'm running on a throw-away docker container so I would not recommend the below as the best solution.

M1 Max 14.4 - Python 3.11 - Ubuntu 20.04 Docker using X86 (AMD64)

The below worked for me (you will have to opt for brew mecab instead):
apt install mecab libmecab-dev

For me, mecab-python3 was installed automatically during the setup as per instructions:
pip install git+https://github.com/myshell-ai/MeloTTS.git

Also (Docker only) if you don't have gcc installed, for some strange reason installing build-essential was the only way to get it to find GCC:
apt install build-essential

For a docker container, you have to install MeloTTS after you create the conda environment with python 3.9, then it should work, does take a really long time to build.

brew mecab is ok

@ahmetkca run brew install mecab first. I have identical specs to you, and had the same issue and that fixed it.
