Snappy configuration failure for SNAP on Mac

I was trying to configure snappy for SNAP. But failing to do so. I am getting some errors which I am attaching in a screenshot!
Can anyone help me with this?

@dolaf could you have a look? Thanks

Hi, as necessary info, could you please provide the SNAP version and the Python version you are using?
Thanks,
Olaf

Snap 8.0
Python 3.6
