python - error: each element of 'ext_modules' option must be an Extension instance or 2-tuple -

-

i trying use setuptools in python create egg package, weird error:

error: each element of 'ext_modules' option must extension instance or 2-tuple

how can fix this?

assuming have setuptools installed, edit setup.py of egg package target , replace import setup, extension in order them setuptools.

from setuptools import setup, extension, command

rational: setuptools redefines extension it's possible not recognize object have in ext_modules argument valid extension object. hence error message.

ext_modules 1 of arguments of setup() method describe extension of module, , it's specified in setup.py.

setup(name='foo',   version='1.0',   ext_modules=[extension('foo', ['foo.c'])],   )

more info available in python documentation
