Expected behavior

Should be able to fetch django from pypi and execute a successful odo push. Even with this failure, it does push the component.

Any logs, error output, etc?

Works for me. I'm on minishift:

$ odo push

Looks like you're having connectivity problems with pip trying to download your dependencies (Failed to establish a new connection):

unable to exec command [/bin/sh -c pip install --user -r requirements.txt]:

Are you using a proxy? Is your minikube installed and configured correctly?

I think my system's minikube might be at a fault here. I ran the same thing from another machine and it worked. Closing this issue.
