Clarify requirements for local setup in README

[eebbesen]

• I get nimby and panda errors when I run pipenv install --dev on OS X
• I'm not sure what Python version I should be using (both 3.5.x and 3.6.x mentioned in the project)
• I'm unclear on whether I should be developing inside the docker container, or just running the app from there

@kjschiroo can you clarify?

[kjschiroo]

Oh boy, it's been a while. I'll take a look.

@eebbesen I'm running on Ubuntu 18 and don't appear to be getting any pandas errors. Could you post what you are hitting? Also do you mean numpy instead of nimby?

[kjschiroo]

Welp, that was an interesting little ponder through past build process decisions. I added a bit of clarifying text to the README to describe how the current dev flow is expected to go (although that process could probably use a good shaking out), feel free to add any further questions to the PR #61 . Given that it addresses those concerns I can merge it in.

I don't think that python3.5 or python3.6 should matter. I'll need to take a look at bumping that in pipenv. Can't remember how much of a pain that makes itself.

@kjschiroo here's what I get when following those instructions for dev setup. I'm on OS X using pyenv to manage my Python versions. (And yes, "numpy" :).)

Here's a gist with the full error: https://gist.github.com/eebbesen/de1dabbc0ae8337dc8cf3bea31d8cf44

Hm... that's odd. It looks like you are trying to build numpy rather than use the pre-built wheels. How old is your version of pipenv/pip?

[eebbesen]

I can try working on it in an Ubuntu VM, though, I'd rather not distract from getting this setup on OS X until we have folks who don't have access to other methods.

pipenv, version 2018.11.26
