Idempotent "pip uninstall"

See original GitHub issue

If I run pip uninstall a b and a is installed but b is not the pip uninstall will error out and not uninstall b - as requested. I think this behavior is very surprising. Pip should maybe warn about packages that are already uninstalled?

IOW, if the goal of uninstall is to remove a package, then if the package is already removed then it’s a success. Why is it an error?

My vote would be to change default return code and to return success if in the end the module is no longer installed. That’s real idempotency, not having to add an additional parameter to obtain that behaviour.

I would very much like an --ignore-missing parameter for pip uninstall. This would be very handy for scripts that want to ensure that packages are in a known state.
