I'm trying to install the opencv-python library on macOS using pip

  pip install opencv-python

I keep encountering this error:

ERROR: Failed to build installable wheels for some pyproject.toml based projects (opencv-python)

pip install --upgrade pip setuptools wheel

I have tried to solve it,

Installed dependencies via Homebrew:

brew install cmake pkg-config libjpeg libpng libtiff openexr eigen tbb ffmpeg

Attempted to manually build OpenCV from source using CMake (installed via Homebrew).

My Setup:

macOS Version: [macOS Big Sur 11.4]

Python Version: [Python 3.10.9]

pip Version: [pip 25.0 from /Users/demo/anaconda3/lib/python3.10/site-packages/pip (python 3.10)]

Question: What am I missing? How can I resolve this issue and successfully install OpenCV in Python on macOS?

The latest opencv-python binary package, currently version 4.11, supports Mac OS 13.0+.

You are not running that.

Depending on your architecture (ARM or not), you might have luck installing an older version, like:

• pip install opencv-python==4.10.0.84 (macOS 11.0+ ARM64)
• pip install opencv-python==4.9.0.80 (macOS 10.16+ x86-64)
