TypeError: unsupported operand type(s) for +: 'Nonetype' and 'list'

I am facing this issue while using 'bench init frappe-bench'. I have downloaded it using 'pip3 install frappe-bench' I found this issue closed but no solution has seemed to work.

/usr/local/Cellar/python/3.7.6_1/bin/python3.7: Error while finding module specification for 'frappe.utils.bench_helper' (ModuleNotFoundError: No module named 'frappe')

I have been trying this for quite some time now and still see the same issue.

Somehow got bench installed but it did so with some warnings, I thought:

But, after that, when we try to use it, it throws the error. It looks like bench was not properly installed:

I see so many people have reported the same issue but no proper answer to it.

Is there really a solution to this issue? Could someone from Frappe tech show some light on this, please?

This error seems to come up when frappe hasn't been installed properly in your bench's env.
