I am trying to install gem pg but keep getting an error returned in my terminal. I have pg installed, i installed it with brew. I ran gem install pg and it just tell me that pg is already installed.

Here is the error I get.

Here's my fix on ubuntu 20.04:

sudo apt install libpq-dev -y

followed by:

gem install pg -v '0.21.0' --source 'https://rubygems.org/'

To tell system to use the gem you have installed on machine

Try 

brew install postgresql

or try 

ARCHFLAGS="-arch x86_64" bundle install

I think I had similar problem on MacOS. Once you installed PostgreSQL viw brew, you need to install pg gem like:

gem install pg -- --with-pg-config=/usr/local/bin/pg_config

Check details here. This worked for my MacOS machine.

Good luck!
