I am missing something, I have downloaded pgadmin4 webapp, and trying to launch it in its environnement:
(pgadmin) denis ~/anaconda3/envs/pgadmin/lib/python3.5/site-packages/pgadmin4 $ pip install flask_babel
Requirement already satisfied: flask_babel in /home/denis/anaconda3/envs/pgadmin/lib/python3.5/site-packages

(pgadmin) denis ~/anaconda3/envs/pgadmin/lib/python3.5/site-packages/pgadmin4 $ sudo python pgAdmin4.py
Traceback (most recent call last):

What can I do more than source activate pgadmin and install all requirements.txt?
Running sudo python doesnt use your virtualenv. Install pgadmin reqs globally or drop sudo.
