Where can I find this version of hub?

After numerous trials, I believe the problem is that I checked out v1.0.0 instead of master.

Then, there are errors during the execution of $ pip3 install -r nrf/scripts/requirements.txt
at building pygit2 and onwards.

Maybe the problem is related to my C compiler installation?
I installed Microsoft community edition on this new Windows laptop.

In that case, what is the recommended tool?

Is there an alternative?
