Installation errors

[jmclaus]

When installing on two different machines (Linux Mint 18.2 & Ubuntu 15.10), I ran into errors when Ansible tried installing certain dev requirements: ipdb and ipython. This can be fixed by locking down the version of these ie by modifying these entries in requirements.dev.txt as follows:

ipdb==0.10.2
ipython==5.3.0

Below are the errors encountered:

Which branch were you trying to install? You probably want to be working with develop

For historical reasons, we don't use master. New work goes into develop and the current production version is in release

FYI @blarghmatey, it looks like these are different requirements issues than the ones you saw yesterday.

@pdpinch Indeed, I first built and set up the dev environment after cloning the git repo and using master. I guess this should be mentioned somewhere in the developer guide to avoid future confusions.

In any case, all is fine, I have a functional dev environment and am doing work on branches based off of develop.

Thanks

@jmclaus, which ansible version are you using?

[jmclaus]

@annagav On the Linux Mint machine, version 2.3.1, on the Ubuntu one , version 1.7.2

I ran into same errors, so I am going to open a PR for this.
