python - Installing numpy as a dependency with setuptools

This might be a follow up question of this one.

I am using setuptools to install a package of mine. As a dependency I have listed numpy. I am using Python2.7 and when I do

python setup.py install

with this setup.py file:

from setuptools import setup

setup(name = "test_pack", install_requires = ["numpy"])

I end up with this error message:

ImportError: No module named numpy.distutils

What do I need to do in order to include numpy as a dependency and install it without having python-dev installed?


The complete output of python setup.py install:

This is a known issue, tracked on numpy/numpy #2434.

I found a workaround for this: add numpy to setup_requires. Having it in both setup_requires and install_requires seems to work fine with the most recent version of setuptools.

So, your setup.py should look something like

setup(
    # Your setup specific stuff here
    setup_requires=["numpy"],  # Just numpy here
    install_requires=["numpy"],  # Add any of your other dependencies here
)
