CAN NOT RUN KRKN pip install fails

[Alejandro Gullón]

I can not run krkn tests because pip3 install -r requirements fails: ERROR: More than one .egg-info directory found in /tmp/pip-pip-egg-info-1cwjqpvc

Then, when I try to run tests:

Traceback (most recent call last):
    File "/opt/tools/krkn/run_kraken.py", line 5, in <module>
          import yaml
ModuleNotFoundError: No module named 'yaml'

I'm using Python 3.9.5 and running this script to test this issue:

#!/bin/bash

python3 -m venv py_env

source py_env/bin/activate

pip install --upgrade pip
pip install -r requirements.txt

python3 run.py

deactivate

run.py

import yaml
print("hello")
