Problem in a python2 file

[Larz60+]

click is available for python 3
make sure your pip is for python 3:

pip -V

you should see something to similar to:

Output:
(venv) Larz60p@linux-nnem: BusinessLists:$pip -V
pip 18.0 from .../BusinessLists/venv/lib/python3.7/site-packages/pip (python 3.7)
(venv) Larz60p@linux-nnem: BusinessLists:$

important thing is that version is python 3+
if not use pip3

pip install click
# or if necessary
pip3 install click
