Question

所以我正在尝试运行rails console但是我收到以下错误：

/var/lib/gems/2.3.0/gems/actionpack-5.1.3/lib/action_dispatch/http/response.rb:89:in `<class:Response>': undefined method `cache_control' for class `ActionDispatch::Response' (NameError)

我尝试重新启动弹簧，但它没有用。有任何想法吗？

编辑：这是我的config / application.rb：

require_relative 'boot'

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module Buzzbomb
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.1
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.
  end
end

这是我的宝石文件：

source 'https://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end

我不确定我做错了什么 - 感谢任何建议，在nginx服务器上运行。它在本地工作但我在服务器上执行“rails console”时出错。

Answer 1

我从Rails 4升级到Rails 5时遇到了同样的错误，结果证明我的Gemfile.lock中的合并错误。

我重新捆绑（site_location），现在又重新开始工作了。

Answer 2

使用rails new my_api --api

生成项目

gem 'actionpack-action_caching'

caches_action :index

得到错误：

app/controllers/api/v1/traces_controller.rb:10:inclass:TracesController': undefined method caches_action' for Api::V1::TracesController:Class (NoMethodError)

UPD好的，如果您的应用程序控制器继承自ActionController :: API，只需：

include ActionController::Caching in application_controller.

Rails控制台无法启动 - 未定义的方法cache_control
