AttributeError: module 'pkgutil' has no attribute 'ImpImporter'

 If you’ve recently upgraded to Python 3.12 or later, you might run into the following error while using pip, setuptools, or related packages:

AttributeError: module 'pkgutil' has no attribute 'ImpImporter'

Why This Error Happens 

Python 3.12 has officially removed support for the legacy imp module, which was deprecated in earlier versions. Some older versions of pip, setuptools, or wheel may still try to reference ImpImporter, leading to this error.

How to Fix It:

Follow these simple steps to resolve the issue:

Step 1: Ensure pip is bootstrapped correctly

Run the following command to upgrade pip using ensurepip: 

python -m ensurepip --upgrade

Step 2: Upgrade pip, setuptools, and wheel 

Once pip is working, upgrade the necessary tools: 

python -m pip install --upgrade pip setuptools wheel

This ensures all the core packaging tools are compatible with Python 3.12 and later.
