One man. One mission. Configure a Vagrant machine with Ansible for use as a Python development environment.

I have attempted to provision a Vagrant machine with Ansible.

I set up my directory structure for it according to the instructions outlined here: https://danielgroves.net/notebook/2014/05/development-environments/

Everything went swimmingly, as shown in the initial part of the response to "vagrant up":

Ultimately, the goal is to get set up for GAE work in Vagrant, with Ansible for automatic provisioning. (This may or may not be a good idea.)

How do I get Ansible to install pip on my Vagrant box?

Really any python provisioning will work.

I have read through the documentation or playbooks and easy_install.

For those worried about the lack of an inventory file, Vagrant creates one on its own. Vagrantup.com has a page on this, which I will post if I get the reputation necessary for it.

I'll go back through this question and revise it after I have thought about this a bit more.

回答1:

It's trying to install pip by using easy_install name=pip. That's outdated, easy_install should no longer be used.

The current approach is to run get-pip.py (see installation instructions). The command to run in Ansible is then python get-pip.py.
