The error is being caused because you're trying to install something that doesn't exist. You've cd'ed into a toga directory, but that directory clearly isn't a checkout of the Toga source tree, because there isn't a src folder under that directory, but there is a range of other code... none of which I can work out where it came from. As a result, pip install fails... because the thing you're asking to install (src/core) doesn't exist.

It's not clear which instructions you're following, because neither the BeeWare tutorial, nor the Toga tutorial would instruct you to run the commands you've described. The instructions you've described are roughly consistent with the developers guide - instructions for someone who wants to set up Toga so they can make a contribution to the project - but you've missed a bunch of steps, and obtained some source code from somewhere that doesn't look at all familiar.
