Я пытаюсь запустить rails db:setup, но что-то не так с Postresql или конфигурацией.Я использую Rails 5.2.2, Linux-машина, ruby ​​2.5.1p57.

Вот ошибка, которую я получаю: 

rails db:setup
rails aborted!
NoMethodError: undefined method `[]' for nil:NilClass

В Rails 5.2 введена концепция учетных данных .По сути, это позволяет нам создавать зашифрованный файл учетных данных, который можно редактировать с помощью файла конфигурации master.key, который используется для расшифровки credentials.yml.enc.В вашем случае файл учетных данных не содержит заголовок электронной почты, который, вероятно, будет иметь следующую структуру в зависимости от вашей конфигурации: 

email:
  username: <String>
  password: <String>
  host: <String>

Вы можете редактировать файл учетных данных, используя EDITOR=vim rails credentials:edit.Если у вас есть проблемы с редактированием файла учетных данных, в этом вопросе есть еще одно обсуждение для того же .Следующие ссылки могут помочь лучше понять учетные данные:
