'Creating new app with rails trying to connect postgresql- error occurred while installing pg
I am trying to create a rails app with postgres and I keep going in circles getting the same errors. I've been scouring the internet for the past two days trying everything and cannot get it to work. Can someone please help me figure this out? I am brand new to rails and new to coding in general.
Here is me first trying to create the app with postgresql as the database:

I'm lost. I've tried brew update, brew install postgresql, gem install pg and brew install libpq. Please help. I used a mac install guide for ruby on rails located here: https://mac.install.guide/rubyonrails/12.html I have an M1 Macbook Air running on MacOS Monterey Version 12.3.1
