Answer 1

So for me and my pals working on a Node.js app (with Postgres and Sequelize), we had to

1. brew install postgresql (one of us was missing postgres, one of us was not, and yet we were getting the same error msg as listed above)

2. brew services start postgresql **** (utilize Homebrew to start postgres)

3. createdb

4. node_modules/.bin/sequelize db:migrate

5. npm start
