Can't install psycopg2 package through pip install… Is this because of Sierra?

Question

I am working on a project for one of my lectures and I need to download the package psycopg2 in order to work with the postgresql database in use. Unfortunately, when I try

Answer 1

env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" \
brew upgrade openssl

Then I could install psycopg2

Answer 2

I fixed it with:

brew reinstall openssl

export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/

Answer 3

This works for me (on a terminal):

find / -name pg_config  2>/dev/null

then add the path:

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.5/bin/

os version: MacOs Sierra

I hope this helps.

Answer 4

It looks like the openssl package is not installed. Try installing it and pip install again. I'm not a macos user, but I believe that brew simplifies package management on that platform.

You might also need to install the Python development and postgresql development packages.

Answer 5

I fixed this by installing Command Line Tools

xcode-select --install

then installing openssl via Homebrew and manually linking my homebrew-installed openssl to pip:

env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install psycopg2

on macOS Sierra 10.12.1

Answer 6

Try installing it with:

pip install psycopg2-binary
