Question

Ruby on Rails uygulamasında yeniyim ve Internet'ten bazı örnekler vermeye çalıştım. Ama kurulum kurulumu yapmaya çalıştığımda bir hatam var. gem devise ekleyerek Gemfile'ı değiştirdim. Ardından, çalıştırdığım zaman çalıştırın:

bundle install 

.

bana yardım edin:

rails generate devise:install 

sonraki hata vardı!

Answer 1

Devise sürümü oldukça eskidir. Sonra

bundle update devise 

Ve:

bunu yapabilirsiniz

bundle install 

Bu Devise mücevher yükseltmelisiniz.

Answer 2

Olmalıdır:

rails generate devise_install 

değil:

rails generate devise:install
