How to install psycopg2-binary on Apple M1

I had some difficulties working with python code accessing postgres databases. Let me show you how I handled it.

Last month I bought to myself an Apple M1, really good computer, with great power, and awesome battery.

My work with it is pretty simple, I code python API, some simple front App with TypeScript/react, trying some Go, learning swift and administrating some kubernetes clusters. Nothing too fancy.

I am trying to work with latest versions of software I use, and in this case, python 3.10.

I installed it with brew, pretty easily :

brew install [email protected]

I had troubles with psycopg2-binary, installing depedencies of one of the projects I work with, the error message i was getting was this one :

Error: pg_config executable not found. pg_config is required to build psycopg2 from source. Please add the directory containing pg_config to the $PATH or specify the full executable path with the option: python build_ext --pg-config /path/to/pg_config build ... or with the pg_config option in 'setup.cfg'.

It seems there is some conf file that is missing. I tried to solve it by installing postgres server to get that missing file :

brew install [email protected]

At this point, brew tell me to setup the path to PG in my PATH, this way (using ZSH, it tells me to write it obviously to .zshrc):

echo 'export PATH="/opt/homebrew/opt/[email protected]/bin:$PATH"' > ~/.zshrc

Now i’m all set, and i can install it the way i want :

pip(3) install psycopg2-binary

Or in my project repository :

pipenv install psycopg2-binary
