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.
