Re: Installing pgAdmin 4 in Runtime Mode (stand alone) in Linux

This is a blog I wrote re installing pg as a web service, your problem is
probably related to Python PATH.

Thanks for the write up. I've been using "Local Mode" and look forward to
trying the runtime. I ran into a couple problems following your
instructions. They are probably quite minor, but I am not a Python guy so I
have no clue as to how to fix the problems.
virtualenv -p python3 gives error:
Already using interpreter /usr/bin/python3
You must provide a DEST_DIR
So I tried virtualenv -p python3 ~/virtualenvs/ which at least doesn't
throw an error but I have no idea if that's correct.

And finally, the moment of truth:
$~/pgadmin4-2.0/runtime/pgAdmin4
Python path: "/home/rich/virtualenvs/pgadmin4/lib/python3.5/site-packages/"

Python Home: ""
Webapp path: "/home/rich/pgadmin4-2.0/web/pgAdmin4.py"
