Issue:

Upon attempting to install Pyspedas using pip, users encounter the following error:

AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?

Cause:

This error results from the removal of the deprecated pkgutil.ImpImporter class in Python 3.12, which affects the functioning of pip.

Solution:

Manually install pip for Python 3.12 using the following commands:

python -m ensurepip --upgrade
python -m pip install --upgrade setuptools
python -m pip install pyspedas

In a virtual environment:

pip install --upgrade setuptools

2. Ensurepip Upgrade

Python includes an ensurepip tool to install pip in an environment. Use it as follows:

Linux/macOS:

python -m ensurepip --upgrade

Windows:

py -m ensurepip --upgrade

Also, upgrade pip:

py -m pip install --upgrade pip

3. Numpy Upgrade

For Python 3.12, numpy version 1.26.4 is required:

pip install numpy==1.26.4

4. Ubuntu-Specific Fix
