When run `pip-compile requirements.in` in macOS12 monterey using venv python-3.9.9, pg_config not found

OS: monterey macOSv12.0.1 python venv: 3.9.9

requirements.in

# To update requirements.txt, run:
#
#    pip-compile requirements.in
#
# To install in localhost, run:
#
#    pip-sync requirements.txt
#

django==3.2.10  # https://www.djangoproject.com/

psycopg2-binary==2.9.2 # https://github.com/psycopg/psycopg2

After i turn on venv, then i type pip-compile requirements.in then i get a bunch of errors about pg_config not found

This is my asciinema https://asciinema.org/a/sl9MqmrayLAR3rRxEul4mYaxw

I have tried env LDFLAGS='-L/usr/local/lib -L/usr/local/opt/openssl/lib -L/usr/local/opt/readline/lib' pip-compile requirements.in but same.

Please advise.

You'll need to install openssl using brew

brew install openssl
brew install postgres       # If not installed and if required

Set the environment variables globally either temporarily by copying the below into the terminal or adding to .bashrc

export LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include"

You'll also need to set the path for PostgreSQL if not set

export PATH=/opt/homebrew/opt/postgresql@11/bin:$PATH

REMEMBER: Replace @___ with your version

Then proceed with requirements.txt

I appreciate the other 2 answers from @Vishnudev and @cetver 🙏

But I tried to install postgresql using brew install and it took a very long time and I still cannot complete after 20 mins.

I figured this out eventually after much googling

Here are my tech specs of my situation:

monterey 12.1.0
Apple silicon
zsh

Concepts

Conceptually, what I did is :

install openssl, turn on all the exports associated with that,
then install libpq, turn on all the exports associated with that,
then turn on python venv

Here are my steps I took. It's entirely possible not all steps are needed. But I have limited time so here they are.

Steps

brew install openssl
put the following in .zshrc export PATH="/opt/homebrew/opt/openssl@1.1/bin:$PATH"
put the following in .zshenv

export LDFLAGS="-L/opt/homebrew/opt/openssl@1.1/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/openssl@1.1/lib/pkgconfig"

source ~/.zshrc
brew install libpq
put the following in .zshrc export PATH="/opt/homebrew/opt/libpq/bin:$PATH"
put the following in .zshenv

export LDFLAGS="-L/opt/homebrew/opt/libpq/lib"
export CPPFLAGS="-I/opt/homebrew/opt/libpq/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/libpq/lib/pkgconfig"

source ~/.zshenv
Turn on venv
Now the installing of psycopg2-binary should work
