Why am I getting "pyenv: pipenv: command not found" when installing PAT?


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


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.


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