Unable to install KNIME AI Extension with KNIME 5.7.0

KNIME Extensions
1

Hi,

I’ve been trying to install the KNIME AI Extension through both KNIME 5.5.1 and KNIME 5.7.0.

I use a Mac 11.7.4 with intel core, I’ve got Python 3.11, Pixi, and Conda installed, and I always have the same error, pasted below.

Could anyone shed some light? I don’t figure out how to bypass it.

Thanks!

An error occurred while installing the items

session context was:(profile=KNIMEProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null → [R]org.knime.python.llm.channel.bin.macosx.x86_64 5.7.0.v202508301209, action=org.knime.conda.envinstall.action.InstallCondaEnvironment$InstallAction).

Running InstallCondaEnvironment action failed

Installing the Pixi environment failed: pixi install failed with exit code 1

Hi
I am not an expert but when I add your error info into an LLM it returns the following info regarding the error pointing to your Mac OS version:

“The error you’re encountering when installing the KNIME AI Extension on your Mac is due to an incompatibility between your macOS version and a specific Python wheel file. The error message explicitly states that the google_crc32c wheel, which is built for macosx_12_0 (macOS 12 and above), “doesn’t match” your system’s capabilities for macosx_11_0 (macOS 11).

The Root Cause

The problem is that the KNIME AI Extension expects to install a Python package (google_crc32c) that is compiled for a newer version of macOS than the one you’re running (macOS 11.7.4). The macosx_12_0 tag in the wheel’s filename indicates it’s built for macOS Monterey (version 12) or newer. Your system, running macOS Big Sur (version 11), cannot use this package.

KNIME’s official system requirements confirm that macOS 12 (Monterey) and above are the only supported macOS versions for their platform. This is likely the primary reason for your installation failure.

Potential Solutions :white_check_mark:

Here are a couple of ways you can try to resolve this issue:

Upgrade Your macOS

The most direct and recommended solution is to update your macOS to a supported version, such as macOS Monterey (12) or Ventura (13). Since your Mac has an Intel Core processor, it can support these newer operating systems, which will allow the KNIME AI Extension to install the necessary Python packages correctly. Upgrading your OS will ensure compatibility not just with KNIME, but with a broader range of modern software.

Thank you very much for your reply @mgirdwood . That would make sense then. I’ll see if I can upgrade my mac :slight_smile:
