Future support to pipenv

This is possible? I could send a PR to improve that.

That might be an idea for the future -- right now our default virtualization system doesn't work well with pipenv -- you get a lot of error messages, which we think can be ignored, but they are distracting. We have a new system in beta which solves that problem but it's probably best to wait until that's fully live before changing this.
