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?

Follow the below steps to install the Setuptools package on Linux using the setup.py file: Step 1: Download the latest source package of Setuptools for Python3 from the website. Step 3: Go to the setuptools-60.5. 0 folder and enter the following command to install the package.
In Fedora, our pip package Recommends setuptools. Practically that means: Majority of users who install pip will get setuptools by default. Users can explicitly uninstall setuptools after installing pip or exclude setuptools when installing pip.
NumPy can be installed with conda , with pip , with a package manager on macOS and Linux, or from source.
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 ) Unless you have access to a binary distribution (pre-compiled/built) for numpy, you'll have to have the python headers available as it needs them to build numpy. This is why most package managers come with pre-compiled versions of these packages. For example you can apt-get install python-numpy, link that into your virtualenv, and when you try to install your program with install_requires=['numpy'] it should see that it's already installed.

To install numpy the setuptools will download the package and compile it from source. However, there are some prerequisites to compile numpy, you can check it here.
_configtest.c:1:20: error: Python.h: No such file or directory
this error indicates that at least you do not have python-dev package installed(if you are using ubuntu/debian).
