rake db:setup возвращается:

rake aborted! 
You have already activated rake 0.9.6, but your Gemfile requires rake 10.1.1. Prepending `bundle exec` to your command may solve this.

Я знаю, что это не проблема с кодом, а теперь он работает на нашем сервере. Какие идеи могут вызвать эту проблему?

Answer 1

'vouchers' вместо '"vouchers"'

Answer 2

Эта ошибка

rake aborted! You have already activated rake 0.9.6, but your Gemfile requires...

это сейчас не важно. Всегда добавляйте свои команды с bundle exec, и все будет хорошо.

Ваш сервер должен работать в среде Rails? Если так, вы должны запустить

RAILS_ENV=production bundle exec rake db:setup

Но это не будет работать в любом случае из-за второй ошибки.

...PG::Error: ERROR: relation "vouchers" does not exist...

Я считаю, что причина этой ошибки здесь:

app/models/bags_discount.rb:7

BagsDiscount модели, вероятно, имеет некоторые scope, который использует vouchers таблицы. Когда вы запускаете db:setup, все связанные с приложением классы инициализируются, но таблицы еще не существуют.

Этот комментарий может быть полезно:

UPD: если вы хотите быстро & грязное решение: просто закомментируйте проблемные строки и раскомментируйте их впоследствии. Это не должно быть слишком опасно для такого рода рейк-задачи.
