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

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

CodePudding user response：

It look like Postgres is not installed or Postgres /bin missing in the PATH variable

$ export PATH=/Applications/Postgres.app/Contents/Versions/<version>/bin/:$PATH
