Fixing Google Cloud CLI Error: "ModuleNotFoundError: No module named 'imp'"

I updated the python version recently and it broke Google Cloud CLI (gcloud) on my machine

Upon attempting to use gcloud auth login, you encounter an error:

    import imp
ModuleNotFoundError: No module named 'imp'

Upon investigation, it turned out

• Checking the Python version reveals it's 3.12.2.
• The imp module was removed in Python 3.12, causing the error for gcloud.

Python 3.12.2 (main, Feb  6 2024, 20:19:44) [Clang 15.0.0 (clang-1500.1.0.2.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information

But I was in a Catch-22 Situation. While the latest gcloud now supports Python 3.12, updating it requires the gcloud components update command, which is unavailable because gcloud is currently broken.

The solution was manually point to Python to version 3.11 and update gcloud components.

Open your .zshrc file (or the appropriate shell configuration file). Add the following line:

Copycopy code to clipboard
export CLOUDSDK_PYTHON="/opt/homebrew/bin/python3.11"

This line sets the environment variable CLOUDSDK_PYTHON to point to your desired Python 3.11 location (replace the path if necessary).

Run source ~/.zshrc (or the appropriate command to source your configuration file). Now, you can execute gcloud components update to update the gcloud CLI to a version compatible with Python 3.12.

By manually setting the CLOUDSDK_PYTHON environment variable to an older, compatible Python version, you can bypass the initial error and successfully update the Google Cloud CLI to a version working with Python 3.12. Remember to adjust the paths based on your specific installation locations.
