Error installing pgadmin on Linux?

Question

linux

Trying to install pgadmin:
pip install pgadmin4-1.0-py2-none-any.whl
Error:

<b>Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-EAWU_D/psycopg2/</b>

psycopg2 already installed:

Various googles gave advice to update packages and psycopg2 itself - it's done. The PostgreSQL server is installed and running.
What else can be done?

Answer 1

The problem was solved with two commands:

apt-get install python-psycopg2          
apt-get install libpq-dev
