doitlive doesn't run on stock CentOS 7

[omkensey]

doitlive successfully installs on CentOS 7 after pip upgrade'ing pip and setuptools, but will not execute a shell script. I have this script:

#!/bin/bash

echo $RANDOM
date +%s
curl https://www.usno.navy.mil/USNO/time | grep "Master Clock"

When I try to play it with doitlive, I get a stack trace:

$ doitlive play ./test.sh 
We'll do it live!
STARTING SESSION: Press Ctrl-C at any time to exit.

Is git installed? I think we might need to catch IOError here to handle if git isn't installed.

[omkensey]

That fixed it! (What's the dependency on git?)

[sloria]

When displaying prompts we attempt to show the current git branch if the cwd is a git repo. But it should fail gracefully when git isn't installed. Would you like to send a PR with the IOError handling? If not, I can probably take care of it over the weekend.

[omkensey]

I've got a bit of a crunch going on this weekend, but I also have a workaround, so if you want to leave this here I'll be happy to take a whack at it later in the week.

Closing for now since this issue is a bit stale. feel free to comment if it's still an issue though
