未定义的局部变量或方法“searchkick”

Question

我正在尝试将Searchkick添加到我的 Rails 应用程序中。我正在按照“入门”页面上的确切说明进行操作，但不断收到以下错误：

Started GET "/airports" for 10.0.2.2 at 2014-05-26 10:20:33 +0000
Processing by AirportsController#index as HTML
Completed 500 Internal Server Error in 26ms

NameError (undefined local variable or method `searchkick' for #<Class:0xb48f3ba8>):
  app/models/airport.rb:2:in `<class:Airport>'
  app/models/airport.rb:1:in `<top (required)>'

  Rendered /home/vagrant/.rvm/gems/ruby-2.1.1@global/gems/actionpack-4.1.1/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (19.8ms)

这是机场模型的样子：

# ./app/models/airport.rb
class Airport < ActiveRecord::Base
    searchkick
end

这就是机场控制器的样子：

# ./app/controllers/airports_controller/rb
class AirportsController < ApplicationController
  def index
    @airports = Airport.all
  end
end

这是什么原因造成的？

Answer 1

重新启动服务器。更改 Gemfile 后必须重新启动服务器。

如果这不起作用，您可以尝试其他事情：

• 添加gem 'searchkick'到 Gemfile
• bundle install
