Issue

When I try to install the Panther Analysis Tool (PAT) by runing make install in my local panther-analysis repository, the following error occurs:

pyenv: pipenv: command not found

Resolution

To resolve this issue:

1. Navigate to your fork of panther-analysis.

2. Run pipenv --rm

3. Run pipenv install

This will install Python 3.11 in your environment.

Cause

This issue occurs when you don't have Python version 3.11 installed. Having Python 3.11 is a required prerequisite for using PAT.
