Comment (by pmav99):

 OK, I see what is going on now.

 You are using Python 3.7. As a a result the {{{shutil_which}}} name is
 [https://github.com/GRASS-GIS/grass-
 ci/blob/a26ceefdc4e14edc0529b90c4d92c0122b6a4d0e/lib/python/script/core.py#L230-L231
 an alias] to [https://docs.python.org/3/library/shutil.html#shutil.which
 shutil.which] function
 [https://github.com/python/cpython/blob/79efbb719383386051c72f2ee932eeca8e033e6b/Lib/shutil.py#L1293
 defined] in the standard library.

 On Python 2 though, shutil_which is the function [https://github.com
 /GRASS-GIS/grass-
 ci/blob/a26ceefdc4e14edc0529b90c4d92c0122b6a4d0e/lib/python/script/core.py#L160
 defined] in {{{scripts/core.py}}}.

 This is why there is this difference. The function in scripts.core is
 never executed in Python 3.
