[GRASS-user] Trying to use GRASS with Jupyter note books in Windows

[Vishal Mehta]

Thanks Markus,
I installed bash kernel; and it seems that it is there (#lsmagic lists bash
as one of the cell magics)

but I get the error below:

##bash
g.list type=rast

---------------------------------------------------------------------------CalledProcessError
                       Traceback (most recent call last)

Also I am unable to install extensions r.stream.distance:

!g.extension r.stream.distance

as well as through the GUI


both give me a "cannot find executable git" error


Best,

Vishal
