I just run this command as a root from terminal and problem is solved,

sudo apt-get install -y postgis postgresql-9.3-postgis-2.1
pip install psycopg2

or

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

Answer 4

Use these following commands, this will solve the error:

sudo apt-get install postgresql

then fire:

sudo apt-get install python-psycopg2

and last:

sudo apt-get install libpq-dev

Answer 5

For Python 3, I did:

sudo apt install python3-dev postgresql postgresql-contrib python3-psycopg2 libpq-dev

and then I was able to do:

pip3 install psycopg2

Answer 6

I was using a virtual environment on Ubuntu 18.04, and since I only wanted to install it as a client, I only had to do:

sudo apt install libpq-dev
pip install psycopg2

And installed without problems. Of course, you can use the binary as other answers said, but I preferred this solution since it was stated in a requirements.txt file.
