Python3.6 not found on Mac while installing docker instance

Hi All,

I have installed a recent version of Docker on Mac and trying to create a docker instance from an online repo.

The script halts at the following place.

/bin/sh: 1: python3.6: not found
ERROR: Service 'base' failed to build: The command '/bin/sh -c python3.6 get-pip.py' returned a non-zero code: 127

Can someone guide me on what to do for installing python3.6?

Any guidance will be much appreciated.

Thanks
Bilal
