Just add Scripts to path (not Scripts/nuitka), and it should run
nuitka.bat. I would guess that the one without an extension is a Unix
shell script of some sort; have a look at it, see if it's a text file
that begins "#!/bin/sh" or similar. Most likely the file sizes of
nuitka and nuitka.bat will be similar - of the order of hundreds of
bytes, even, as they're probably just invoking Python.

I tried that, and it still gives me the same message.
This is the Windows path, right?  In it, among other
paths, I have:

    C:\Python27\Scripts\

(or without the last "\" also, though it should
not matter, right?)

The nuitka file starts with 

    #!C:\Python27_32\python.exe

and is a Python script. It says in a docstring, 

""""
This is the main program of Nuitka, it 
checks the options and then translates
one or more modules to a C++ source code 
using Python C/API in a build directory
compiles it to either an executable or an 
extension module that can contain other 
modules. """

I'm confused as to why it's not just a .py
file.  The nuitka.bat, aside from some
remarks, is this:

    @echo off
    setlocal

    "%~dp0..\python" "%~dp0nuitka" %*

    endlocal

On a Unix system, you'd execute that with the name "nuitka". Although
it seems to have had your Windows Python executable's path patched in,
which presumably would be replaced with /usr/bin/python or something
on Unix.

And that's just calling on Python. I'm not familiar with the %~dp0
notation, but I'd say it's taking %0 (the name of the batch file) and
taking just the drive and path from it. This should work, once you
have your Windows path pointing to this directory.

The one thing I'm seeing here is that your PATH has
C:\Python27\Scripts\ but your script says C:\Python27_32\python.exe -
what is the actual directory name for your Python directory? Did you
rename it? It could be that something unrelated is causing problems.

On Linux, the `nuitka` script would be run.  Things in $PATH tend not
to have an extension, and you don’t need one to run Python.  (you
can’t import files that don’t end in .py, though)

This is a very fancy way of running Nuitka in the local python
interpreter, with all the arguments.  For example, this:

    C:\Python27\Scripts\nuitka.bat foo bar

will make the script run:

    C:\Python27\python C:\Python27\Scripts\nuitka foo bar

This is to make Windows users’ life easier, to provide them
executables that work just as `nuitka` (and not `nuitka.py`).
However, a more modern method than the one used here is setuptools
entrypoints, which produces a nicer .exe file.

I presume you can learn the same way many of us learn. But reading up on
it and trying things out.  I bet there's even a MinGW list.  Really it's
standard command-line stuff. Learn how to use a unix command line and
you'll be able to grasp it all rather easily I think.  Good luck.

Have you tried it?

I tried it a few months back... it turned out that its not one (turnkey)
solution but a whole setup in which dozens (hundreds?) of
programs need to be selected (like in synaptic) almost like setting
a full-scale linux box from scratch.

Then after that there is the wrestling with library paths...

In the end I found setting up ming in linux with apt and trying out the results
in wine was less taxing.

[Of course I freely admit that linux is generally less taxing (to ME) than
windows]
