Espruino Build issues using README_BuildProcess.md and Extending+Espruino+1 within Windows10 environment

Sun 2019.09.29

Spin off from suggestions in a completely separate thread topic started at:

From that link,
A special Thank You @Wilberforce #6, @Gordon #17, and @AkosLukacs #8 for the step-by-step detail.

Had a bit of down time to make my first pass attempt, and quite frankly a bit overwhelmed, mostly from new terms and new language obstacles not having experience with WSL, Linux, Python and VSCode. Made tremendous progress thanks to @AkosLukacs, but still stuck at a possible basic setup issue.

https://github.com/espruino/Espruino/blob/master/README_BuildProcess.md

Should I execute from the terminal window within VSCode:

Terminal >> Run Active File

> Executing task: echo Hello <

Hello

Terminal will be reused by tasks, press any key to close it.

So, first guess is that VSCode is allowing WSL to function.

Then on to executing a Python file in the same manner.

Should I execute from the terminal window BOARD=PICO_R1_3 make

Terminal >> Run Build Task

rgc@DESKTOP-R7T0VUC:/mnt/c/Users/robin/Documents/Espruino$ /mnt/c/Users/robin/Documents/Espruino/scripts/build_board_json.py
-bash: /mnt/c/Users/robin/Documents/Espruino/scripts/build_board_json.py: /usr/bin/python: bad interpreter: No such file or directory
rgc@DESKTOP-R7T0VUC:/mnt/c/Users/robin/Documents/Espruino$ BOARD=PICO_R1_3 make
/bin/sh: 1: python: not found
make: Nothing to be done for 'all'

But, the Python script ran, so the Python Extension for VSCode should be functioning. (only uninstall visible) and the file build_board_json.py is present from the clone process.

So, it appears I'm stuck at the same 'Rookie' mistake, @AkosLukacs warns about perhaps?

To keep things tidy in Windows10, I attempted cd ~ as in step 3 from AkosLukacs #8
But that placed the contents in the 'Users' folder, and code isn't easily backed up as compared to when within the 'Documents' folder

I changed that to cd Documents then ran the git clone instruction

So from the Windows point of view, the cloned files are now at C:\Users\robin\Documents\Espruino\

and from WSL are at /mnt/c/Users/robin/Documents/Espruino

Also looked over @JumJum 's 'C' extension tutorials for hints ideas etc

The obvious stand out to anyone?
