Installation is redirecting to Python 2.7 from system and not using Python just inside conda.

It seems problem is in "pip2", from Makefile.

Short answer, upgrade pip:

$ pip2 install --upgrade pip

Long answer: If you are manually installing ORP then you might have issues following the installation instructions because the version of Python in the Dockerfile is Python 2. You need to make sure your pip2 version is new enough to support smart installation using wheel packages.
