Unable to run trape.py

error when command python2 trape.py is run

Traceback (most recent call last):
File "trape.py", line 24, in
from core.trape import Trape
File " /home/kali/Desktop/trape/core/trape.py", line 304 in
readline.set_completer(utils.niceShell)
AttributeError: 'module' object has no attribute 'niceShell'

Notes:
* Updated pip for python2 and installed all the requirements from requirements.txt

Reproduce the failure with `python2 trape.py`, then inspect `core/trape.py` around line 304 and the referenced `utils.niceShell` entry point. Done means the command starts without the reported AttributeError and the relevant regression is covered by a test if the repository provides one.
