Ruby On Rails - NoMethodError: неопределенный метод `[] 'для nil: NilClass

Question

Я пытаюсь запустить на новом компьютере какой-нибудь код ruby ​​и получаю следующую ошибку (rails db: migrate --trace)

** Invoke db:migrate (first_time)
** Invoke db:load_config (first_time)
** Invoke environment (first_time)
** Execute environment
rails aborted!
NoMethodError: undefined method `[]' for nil:NilClass

конфиг / Инициализаторы / stripe.rb

Rails.configuration.stripe = { 
  publishable_key: Rails.application.credentials[Rails.env.to_sym][:stripe][:public_key], 
  secret_key:      Rails.application.credentials[Rails.env.to_sym][:stripe][:secret_key] 
} 
Stripe.api_key = Rails.configuration.stripe[:secret_key]

Answer 1

Из отправленной вами стековой трассировки, в частности, возникает проблема с этой строкой:

Rails.application.credentials[Rails.env.to_sym][:stripe][:public_key]

Поскольку вы объединяете несколько хэшей, один из этих объектов - nil. Вы можете попробовать проверить каждый из них, добавив что-то вроде этого в начало инициализатора:

puts Rails.application.credentials.inspect
puts Rails.application.credentials[Rails.env.to_sym].inspect
puts Rails.application.credentials[Rails.env.to_sym][:stripe].inspect

Это скажет вам, какой части nil не должно быть, и вы можете соответствующим образом обновить свой файл учетных данных.
