How to fix " ERROR: Could not build wheels for TA-Lib, which is required to install pyproject.toml-based projects" on M1 macs

Troubleshooting TA-Lib Installation for Python on MacOS

Note: This guide assumes you have already installed TA-Lib on MacOS using the following command:

brew install ta-lib

If you encounter errors during the Python TA-Lib installation due to potential incompatibilities or misconfigurations, follow the steps below to troubleshoot:

1. Ensure TA-Lib C library is correctly installed

First, validate that the TA-Lib library installed via Homebrew is properly set up. Execute the following command:

ta-lib-config --cflags --libs

This should reveal the configuration for the C library. If the output isn't as expected, there might be an issue with the TA-Lib C library installation.

2. Check for Multiple Python Versions

Having multiple installations of Python could cause conflicts. Make sure to use the correct Python version or environment when using pip. If utilizing virtual environments, activate the appropriate one beforehand.

3. Install TA-Lib for Python with Specific Flags

On occasion, the installation might not automatically locate the TA-Lib C library from Homebrew. In such scenarios, specify the paths manually during installation:

pip install TA-Lib --no-binary=TA-Lib -v --global-option=build_ext --global-option="-L/opt/homebrew/lib/" --global-option="-I/opt/homebrew/include/"

This command designates the library (-L) and include (-I) directories to guide the installation process.
