I'm trying to deploy a rails app, but it is failing due to below error in the build step. I'm using 'pg' gem.

Try adding this nixpacks.toml file to your project -
[phases.setup]
nixPkgs = ["...", "postgresql"]a year ago
It is not working. Still getting the same error.

You are using a Dockerfile not nixpacks, please attach the Dockerfile instead.

No, I’m not using docker. It’s just a plain ROR app.
Are there any additional files/config to be setup for deploying rails app?

You are not installing the postgres client so therefore the postgres client would not be available to your app.

I managed to fix it and my app is now live, Thank you so much for helping.
