ruby-on-rails - 更好的错误 Gem 无法在本地浏览器中运行，没有可见的错误

Question

我将 Better Errors gem 添加到我的 gemfile 中，如下面的 gemfile 所示，然后运行 ​​bundle 并看到 Using better_errors 1.1.0并多次重新启动我的服务器。我观看了有关如何安装它的 railscast 剧集。过去我在安装任何其他 gem 时从来没有遇到过问题(我是编程新手)。我阅读了文档，并且已经对此进行了检查:

Note: If you discover that Better Errors isn't working - particularly after upgrading from version 0.5.0 or less - be sure to set config.consider_all_requests_local = true in config/environments/development.rb.

任何关于如何让这个 gem 工作的想法将不胜感激!这是我的 gem 文件:

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.5'

group :development, :test do

  gem 'rspec-rails'
  gem 'capybara'
end


# Use sqlite3 as the database for Active Record
 group :production do
   gem 'pg'
   gem 'rails_12factor'
 end

 group :development do
   gem 'sqlite3'
   gem 'better_errors'
 end

 gem 'bootstrap-sass', '~> 3.1.1'

# Use SCSS for stylesheets

gem 'uglifier', '>= 1.3.0'

# Use CoffeeScript for .js.coffee assets and views

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

# Use ActiveModel has_secure_password

使用 Vagrant，将其添加到您应用的 config/environments/development.rb (configure block 内的任何位置):

BetterErrors::Middleware.allow_ip! "0.0.0.0/0"

然后重启你的服务器。

(这只是 Sasha 解决方案的一个细微变化。)

DO NOT add this to your production environment!
