Issue while installing python dependencies on mac

[luca gregnanin]

Dear users,

I'm new to partitionfinder2 and I have no experience in using Python.

I use MacOS Big Sur.

I tried to install python 2.7 with anaconda distribution, but I'm not sure of where I can find a proper installer for this, since it is not clear to me which python version comes with each anaconda distribution.

I installed python version 2.7.13 from https://www.python.org and it should be correct.

I then tried to install the required packages with pip, but it seems python cannot install them. I attach a screenshot of my terminal window.

How can I solve this? 

Any help will be greatly appreciated. Thank you in advance!
