ERROR: Exception: Traceback - PIP3

[RessBB]

Hello, I would like to try this software on my PC which is running FossaPup64. Unfortunatelly i have some difficulties with it. To be more concrete i forced these errors in Terminal app:

root# python setup.py
sh: pip: command not found
Traceback (most recent call last):
File "de.py", line 11, in
exec(decoded_content)
File "", line 4, in
ModuleNotFoundError: No module named 'bs4'

then I have tried this command but get another error message:

root# pip3 install -r requirements.txt
ERROR: Exception:

I will really appreciate if anybody helps me solve this, since Im not very experienced in compiling python.
I would really like to test this program also :)))
