Answer 1

$ find / -name pg_config 2>/dev/null

/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config

$ export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.3/bin/

$ pip install psycopg2

Answer 2

My issue was that for some reason from within VENV pip install psycopg2 does not work but I found that running this command from inside of VENV

env LDFLAGS='-L/usr/local/lib -L/usr/local/opt/openssl/lib -L/usr/local/opt/readline/lib' pip install psycopg2

allow me to install it on mac.

Answer 3

If you use Docker and you do not want to install postgresql in you host system, you can try to use package psycopg2-binary and use postgresql in container.

Answer 4

To install psycopg2 you need have installed server before( I have installed PostgresApp)

Run manually command including the path of pg_config program in PATH env variable, in my case:

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.4/bin/

and then run

pip3 install psycopg2

EDIT:

Check directory of pg_config:

which pg_config

Answer 5

On my MAC, this did the trick:

pip install psycopg2-binary

I was fighting with this issue for a complete day. Then I ran a script that I found in Pillow library Issues and solve the problem. Check it out https://github.com/python-pillow/Pillow/issues/3438#issuecomment-435169249
