pip3 instead of pip in install docs

[mzac]

Issue type: Bug report

Python version: 3
NetBox version: 1.9.5

While reading the install docs I decided to use Python 3 however getting to the step of 'pip install -r requirements.txt' this failed, the documentation needs to have 'pip3 install -r requirements.txt' added if you are using python3.

Can you please provide a detailed account of the installation procedure you followed?

There was a discussion in the Google group about this as well:

Turns out there are several issues when only Python 3 is installed (on Ubuntu, at least).

• Ubuntu has different packages for psycopg2 under Python 2/3
• Ubuntu does not provide /usr/bin/python (only /usr/bin/python3)
• Ubuntu does not provide /usr/bin/pip (only /usr/bin/pip3)

Glad you found the fix :) I'm still quite new to python so I wasn't sure if I was missing something but it looks like I'll give it a retry on python 3 instead of python 2 now...

Prior to releasing v2.0 which will require Python3 we should make sure that the docs for both Ubuntu and RHEL/Cent are firm otherwise I can foresee a large inrush of related issues.

[jeremystretch]

I've worked through a few Ubuntu and CentOS installations using Python 3 and I think this has been sorted. I'm going to close out this issue but please feel free to re-open or open a new one as appropriate for any outstanding issues.

Prior to releasing v2.0 which will require Python3

NetBox v2.0 won't require Python3 (although it's strongly encouraged). We'll still be on Django 1.11. Django 2.0 will drop support for Python3, but we probably won't move to Django 2.0 until sometime in early 2018. No promises, though.
