pgadmin4 - New install not working

Question

I downloaded the postgresql-9.6.0-1-linux-x64.run package and ran through the installer on ubuntu 16.04. Postgres is working fine. I am trying to use the pgadmin4 package that was included with this installer. I created a site in Apache per the instructions.

This is the error I am getting in the server.log file in Apache. Not sure how to fix this.

   Traceback (most recent call last):

File "/opt/PostgreSQL/9.6/pgAdmin4/web/pgAdmin4.wsgi", line 8, in <module>
     from pgAdmin4 import app as application

File "/opt/PostgreSQL/9.6/pgAdmin4/web/pgAdmin4.py", line 24, in <module>
     from pgadmin import create_app

  from flask_babel import Babel, gettext

ImportError: No module named flask_babel

Answer 1

This error message shows that your environment is missing a package called flask_babel. To install it, switch to the virtualenv your webserver uses and install it with this command:

pip install flask_babel

If you are not using any virtual environment for your python scripts, you have to prepend sudo to the command. But you should really consider using a virtualenv for your projects.

Answer 2

If you are using virtualenv to run pgAdmin4 then you need to activate it first, Refer Apache mine wsgi file.
