Error trying to install Postgres for python (psycopg2)
The python-dev package is required for compilation of Python extensions written in C or C++, like psycopg2. If you're running a Debian-based distribution (e.g. Ubuntu), you can install python-dev by running
sudo apt install python-devor
sudo apt install python3-devdepending on your python version (for example, sudo apt install python3.8-dev).
After that, proceed to install psycopg2 in your virtualenv environment as usual.
For Ubuntu 14.04, from Docker image python:3.4.3-slim this combination worked for me:
sudo apt-get updatesudo apt-get install -y build-essentialsudo apt-get install -y python3.4-devsudo apt-get install -y libpq-devpip3 install psycopg2Note build-essential package. It was crucial in my case.
