• python --version - Python 3.4.3

• which pip3 - /usr/bin/pip3

Você pode por favor me ajudar a resolver este problema?

Você está enfrentando o seguinte erro:

  

Exceção: a ferramenta pg_config não está disponível.

A ferramenta pg_config faz parte de libpq-dev

Você pode instalá-lo usando:

sudo apt-get install libpq-dev
