I am having an issue while trying to connect with a PG database in my Rails application:
I've create my new app with the following command:
$ rails new -d postgresql myApp
The application was created successfully. Therefore I proceed with the following command:
$ createuser --createdb --login -P myApp
The prompt asks me a password for a new role. I enter the password and re-enter it for confirmation. This the message I get after entering the password:
createuser: could not connect to database postgres: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
Any help? I am using PG version 9.5.3 and Ruby on Rails version 4.2.4
