的Rails的SyntaxError

Question

每當我開始我的Rails服務器，我發現了以下錯誤：

SyntaxError - /Users/Bangner/Desktop/wednesday/myapp/vendor/bundle/gems/devise-3.1.0/app/controllers/devise/sessions_controller.rb:52: syntax error, unexpected keyword_end, expecting end-of-input: 
    zeus (0.13.3) lib/zeus/load_tracking.rb:50:in `' 
    zeus (0.13.3) lib/zeus/load_tracking.rb:50:in `load' 
    zeus (0.13.3) lib/zeus/load_tracking.rb:50:in `load' 

我的會話控制器：

class Devise::SessionsController < DeviseController 
    prepend_before_filter :require_no_authentication, :only => [ :new, :create ] 
    prepend_before_filter :allow_params_authentication!, :only => :create 
    prepend_before_filter { request.env["devise.skip_timeout"] = true } 

    # GET /resource/sign_in 
    def new 
    self.resource = resource_class.new(sign_in_params) 
    clean_up_passwords(resource) 
    respond_with(resource, serialize_options(resource)) 
    end 
    end 

    # POST /resource/sign_in 
    def create 
    self.resource = warden.authenticate!(auth_options) 
    set_flash_message(:notice, :signed_in) if is_navigational_format? 
    sign_in(resource_name, resource) 
    respond_with resource, :location => after_sign_in_path_for(resource) 
    end 

    # DELETE /resource/sign_out 
    def destroy 
    redirect_path = after_sign_out_path_for(resource_name) 
    signed_out = (Devise.sign_out_all_scopes ? sign_out : sign_out(resource_name)) 
    set_flash_message :notice, :signed_out if signed_out && is_navigational_format? 

    # We actually need to hardcode this as Rails default responder doesn't 
    # support returning empty response on GET request 
    respond_to do |format| 
     format.all { head :no_content } 
     format.any(*navigational_formats) { redirect_to redirect_path } 
    end 
    end 

    protected 

    def sign_in_params 
    devise_parameter_sanitizer.sanitize(:sign_in) 
    end 

    def serialize_options(resource) 
    methods = resource_class.authentication_keys.dup 
    methods = methods.keys if methods.is_a?(Hash) 
    methods << :password if resource.respond_to?(:password) 
    { :methods => methods, :only => [:password] } 
    end 

    def auth_options 
    { :scope => resource_name, :recall => "#{controller_path}#new" } 
    end 
end

第11行你有一個額外end聲明。

def new 
    self.resource = resource_class.new(sign_in_params) 
    clean_up_passwords(resource) 
    respond_with(resource, serialize_options(resource)) 
    end ### <--- this is the line that's causing your error 
    end
