I build a development environment using vagrant and virtualenv/virtualenvwrapper. Recently, my vagrant box stopped provisioning correctly. It seems virtualenvwrapper won't install anymore. I am trying to trace down what has changed. What has changed?
My Vagrantfile and install.sh files are here: https://gist.github.com/ErikEvenson/9763878. Note that this error happens on the web box.
This is the error I get when I try to install virtualenvwrapper:
vagrant@vagrant-ubuntu-precise-64:~$ pip install virtualenvwrapper

----------------------------------------
Command python setup.py egg_info failed with error code 1
Storing complete log in /home/vagrant/.pip/pip.log
Running pip install --upgrade pip after doing apt-get install python-pip seems to have done the trick. This bring pip up to 1.5.4 and avoids the error above. Also, be sure to use /user/local/bin/pip for the rest of the provisioning script.
I'm not sure what changed to make my provisioning dependent on pip > 1.0 though. Would be nice to know so that I can lock that dependency down.
