When I try to create conda environment

sudo conda create -n dato-env python=2.7 anaconda

I get

conda doesn't play well with sudo. The purpose of conda or virtualenv is to create an environment which is isolated from the system root environment.

But it gives same result without sudo too

This seems like a anaconda issue. Please contact https://www.continuum.io/ for support.
