Checking your repo I found that get_path_pandoc, the function from which
you took the code snippet above, will always return None if
os.path.isfile(path_pandoc).
This is probably not what you are intending. Do you know if path_pandoc
is maybe set to an existing file in your frozen code already so the
whole 'which' or 'where' branch is never executed?
