Unable to install on Python 2.7

[rparini]

I can't get numdifftools to install with python 2.7. I resolved the error

RuntimeError: Due to a bug in setuptools, PyScaffold currently needs at least Python 3.4! Install PyScaffold 2.5 for Python 2.7 support.

by changing in setup.py

setup(setup_requires=['pyscaffold>=3.0a0,<3.1a0'] + sphinx,

to

setup(setup_requires=['pyscaffold==2.5.10'] + sphinx,

(2.5.10 is needed to work with setuptools version >= 39 due to pyscaffold/pyscaffold#148). But I then get the error

error: 'egg_base' must be a directory name (got `src`)

which is the setuptools bug that the PyScaffold docs say you need to use PyScaffold 2.5 to avoid. It might be that the project needs to be set up with PyScaffold 2.5 in the first place as well as installed with it. When I go back to the commit 406a798 (just before numdifftools was updated with PyScaffold 3) then I can get it to install on python 2.7 if I downgrade setuptools to < 39.

Thanks for reporting. I will look at it soon.

Ok. I have reset the setup.py to

setup(setup_requires=['pyscaffold==2.5.11'] + sphinx,

Then it works for python version 3.4, 3.5 and 3.6, but not 2.7. It seems to me that this is actually a bug in setuptools: pypa/setuptools#1136.

Setting setup.py to

setup(setup_requires=['pyscaffold==2.5.11'] + sphinx,
       package_dir = {'': 'src'},
       packages=find_packages(where=r'./src'),...

seems to be a workable solution in commit 7db83c8.

Therfore I am closing the issue.

Yes, this works for me now, thank you.
