Python 3 is sometimes installed as python on systems. #85

Closed DaveAtKitronik closed 3 years ago

Trying to build following the instructions I got a slightly cryptic error: $ make V=1 -C lib/micropython/mpy-cross make: Entering directory '/home/Dave/micropython-microbit-v2/lib/micropython/mpy-cross' python3 ../py/makeversionhdr.py build/genhdr/mpversion.h make: python3: No such file or directory make: *** [../py/py.mk:246: build/genhdr/mpversion.h] Error 127 make: Leaving directory '/home/Dave/micropython-microbit-v2/lib/micropython/mpy-cross'

I initially thought it had come from python, but its from make complaining it cant find python (I really should read more carefully) I am building on a clean Cygwin installation - where python 3 is installed as python this is fixed by making a symlink: ln /usr/bin/python /usr/bin/python3

I had this same issue previously when working on the V1 micropython, but had forgotten it. A small addition to the readme to mention it would have saved me a few hours, and potentially others as well.
