完成RailsTutorial.org后，我决定 i18n 我的应用程序，突然我的测试开始失败，出现以下问题，
失败：
1) 用户页面索引失败/错误：登录用户 Capybara::ElementNotFound: Unable to find field "Email" # ./spec/support/utilities.rb:5:in
sign_in' # ./spec/requests/user_pages_spec.rb:11:inblock (3 levels)
我所做的唯一改变是，
路线.rb
SampleApp::Application.routes.draw do
scope '(:locale)' do
resources :users
resources :sessions, only: [:new, :create, :destroy]
root to: 'static_pages#home'
match '/signup', to: 'users#new', via: 'get'
match '/signin', to: 'sessions#new', via: 'get'
match '/signout', to: 'sessions#destroy', via: 'delete'
match '/help', to: 'static_pages#help', via: 'get'
match '/about', to: 'static_pages#about', via: 'get'
match '/contact', to: 'static_pages#contact', via: 'get'
end
和 config/initializers/i18n.rb
I18n.default_locale = :en
LANGUAGES = [
['English', 'en'],
['Portuguese', 'pt']
]
在 i18n 之前，路线如下所示，
users_path GET /users(.:format) users#index
POST /users(.:format) users#create
new_user_path GET /users/new(.:format) users#new
edit_user_path GET /users/:id/edit(.:format) users#edit
user_path GET /users/:id(.:format) users#show
PATCH /users/:id(.:format) users#update
PUT /users/:id(.:format) users#update
DELETE /users/:id(.:format) users#destroy
sessions_path POST /sessions(.:format) sessions#create
new_session_path GET /sessions/new(.:format) sessions#new
session_path DELETE /sessions/:id(.:format) sessions#destroy
root_path GET / static_pages#home
signup_path GET /signup(.:format) users#new
signin_path GET /signin(.:format) sessions#new
signout_path DELETE /signout(.:format) sessions#destroy
help_path GET /help(.:format) static_pages#help
about_path GET /about(.:format) static_pages#about
contact_path GET /contact(.:format) static_pages#contact
现在，
users_path GET (/:locale)/users(.:format) users#index
POST (/:locale)/users(.:format) users#create
new_user_path GET (/:locale)/users/new(.:format) users#new
edit_user_path GET (/:locale)/users/:id/edit(.:format) users#edit
user_path GET (/:locale)/users/:id(.:format) users#show
PATCH (/:locale)/users/:id(.:format) users#update
PUT (/:locale)/users/:id(.:format) users#update
DELETE (/:locale)/users/:id(.:format) users#destroy
sessions_path POST (/:locale)/sessions(.:format) sessions#create
new_session_path GET (/:locale)/sessions/new(.:format) sessions#new
session_path DELETE (/:locale)/sessions/:id(.:format) sessions#destroy
root_path GET /(:locale)(.:format) static_pages#home
signup_path GET (/:locale)/signup(.:format) users#new
signin_path GET (/:locale)/signin(.:format) sessions#new
signout_path DELETE (/:locale)/signout(.:format) sessions#destroy
help_path GET (/:locale)/help(.:format) static_pages#help

有人可以为初学者提供一些提示吗？感谢所有的支持。
