Cannot install via ```python setup.py install``` if using setuptools-scm for getting version.

I have tried to install making sure all the required package are in place. I get the following error when python setup.py install in conda:

Traceback (most recent call last):

    raise OSError("%r was not found" % name)
OSError: 'git' was not found

When I changed the line 82 of the setup.py from use_scm_version=True, to version=0.17,, the installation worked.

Interesting, looks like your system doen't have Git avalable on the command line (which rather messes up the ability to determine the version of the package from Git).

Doing conda install git in either the root environment or the environment you are using before attempting install should solve this. If you don't want to install git then this may be harder to solve.

I'll have a think as using SMC was supposed to avoid the need to explicitly change the version number in files as well as in the version control system (DRY). There may be an easy fix for this (including a different way to read the visrson from git) but equally may also be a bit of a nightmare.

Would not listing git as a required package solve this, then?
