Missing dependency "future" on Python 2.7

[laurent-laporte-pro]

Hi,

When installing Meza v0.41.1 on Python 2.7, the dependency "future" is not installed (but required).

To reproduce (for instance on Windows but the problem is the same on Linux):

D:\Laurent\Projets\virtualenv>C:\Python27\python.exe -m virtualenv meza
New python executable in D:\Laurent\Projets\virtualenv\meza\Scripts\python.exe
Installing setuptools, pip, wheel...done.

D:\Laurent\Projets\virtualenv>meza\Scripts\activate

(meza) D:\Laurent\Projets\virtualenv>pip --version
pip 19.0.1 from d:\laurent\projets\virtualenv\meza\lib\site-packages\pip (python 2.7)

(meza) D:\Laurent\Projets\virtualenv>pip install meza==0.41.1
[...]

(meza) D:\Laurent\Projets\virtualenv>pip list

As you can see, future is missing.

The problem occurs because the Wheel meta info is not valid.

If you want to install "future" only for Python 2.7, your requirements should be:

    'future>=0.16.0,<1.0.0; python_version < "3"'

Thanks for the info. Just dropped support for py2 via a56b927. However, I'm happy to accept a PR off of v0.41.1 (cb28f48).

It's been four years. It's probably not worth considering Python 2.7 any longer.
