Ошибка консоли Rails

Question

Я пытался настроить свой стек рельсов в течение самого длительного времени, и до сих пор я был в состоянии запустить все, но я получаю эту ошибку, когда я пытаюсь запустить консоль рельсов:

Я видел различные исправления в Интернете, но они не решили проблему. Просто интересно, есть ли у кого-то еще такая же проблема или знает, как ее исправить. Спасибо.

Database.yml:
# SQLite version 3.x
# gem install sqlite3
development:
  adapter: mysql
  database: shovell_development
  pool: 5
  timeout: 5000
    username: root
    password: randompassword12
    host: localhost

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql
  database: shovell_test
  pool: 5
  timeout: 5000
    username: root
    password: randompassword12
    host: localhost

production:
  adapter: mysql
  database: shovell_production
  pool: 5
  timeout: 5000
    username: root
    password: randompassword12
    host: localhost

Answer 1

Проблема связана с форматированием вашего database.yml файла. Строки под timeout: 5000 не должны быть с отступом, то есть:

development:
  adapter: mysql
  database: shovell_development
  pool: 5
  timeout: 5000
  username: root
  password: randompassword12
  host: localhost

Answer 2

username, password и host слишком много отступов. Они должны иметь отступы, аналогичные другим параметрам под каждым именем среды.

Answer 3

Просто удалите пробелы в левой части имени пользователя, пароля и хоста, чтобы выровнять его, и попробуйте.
