[ Python 2.7 ]Package program with Pynsist

I am packaging a Python 2.7 program with the lastest version of Pynsist.
I’ve created an installer.cfg file following this example.
But when I try to package my application running

pynsist installer.cgf

into the application folder it comes up with

Copying Python installer to build directory
PyLauncher MSI already in build directory.
Copying packages into build directory...
Traceback (most recent call last):

    raise ExtensionModuleMismatch(extensionmod_errmsg % ('Windows', path))
nsist.copymodules.ExtensionModuleMismatch: Found an extension module that will not be usable on Windows:
/usr/lib/python2.7/dist-packages/pygame/rwobject.so
Put Windows packages in pynsist_pkgs/ to avoid this.

So the problem I think is with Pygame.

On Google there in nothing about this, but i cannot use others programs for packaging(eg. py2exe, pyinstaller ecc…).
Thanks and sorry for the bad english

Answer

Reposting as an answer, since it worked:

If you put pygame in packages=, it tries to copy it from your computer. But on your computer that’s pygame for Linux, which won’t work on Windows. If you instead put pygame in the pypi_wheels= bit of the config file, Pynsist will take care of downloading a Windows version for you.

Have a look at the pygame example in the Pynsist repository.

Most packages don’t have this problem because they only contain Python code, which is the same files on all platforms. Pygame has compiled modules, which have to be compiled for the right platform.
