Question

我刚刚改变了我的Rails 2.3.8项目，使用Bundler加载gems，而不是默认的Rails 2.3加载机制。我跟着the official instructions，该网站在开发中运行良好。我使用RVM进行gem管理，并为应用程序加载了特定的gemset。

然而，我的RSpec测试套件无法运行。我尝试使用各种命令运行整个套件和单个测试：

autospec # My usual way of running tests
rake spec
spec .
spec spec/models/comment_spec.rb # Trying a single spec file in isolation
ruby spec/models/comment_spec.rb

我也试过运行它们所有前缀为bundle exec。一切都返回相同的错误：

我很确定这个问题与Inherited Resources gem无关 - 我认为此时根本没有加载gems，而且Inherited Resources恰好是第一个需要的。

令我感到困惑的是/activesupport-2.3.8/lib/active_support/dependencies.rb:158在初始化阶段需要/app/controllers/admin/base_controller。它不应该那样做，并且肯定不会在开发模式下这样做。我可以在我的Gemfile中注释掉gem 'inherited_resources'，网站仍在运行。直到我点击一个加载使用继承资源的控制器的操作，我才得到“未初始化的常量”错误。

为清楚起见，这是我的Gemfile and spec_helper.rb。

Answer 1

即使是较老的问题，但我对Bundler 1.0.3，Rspec-Rails 1.3.3＆amp; Rails 2.3.8并且能够将其归结为非凡的行业。 Remarkable-Rails似乎在环境运行初始化程序之前加载rspec / rails。

添加后：require =＆gt;在Gemfile中没有它，并且在spec_helper中需要它在需要rails-environment之后问题就消失了。

Answer 2

我意识到这是一个老问题，但我遇到了同样的问题。

我的应用程序需要1.3.0版本的rspec和rspec-rails。看看rspec-rails changelog，我发现在1.3.0之后有一些错误修复。将rspec-rails升级到1.3.2可以解决所有问题。

Answer 3

为了解决这个问题，我改变了Gemfile：

gem 'rspec-rails', '~> 1.3.2', :require => 'spec/rails'

到

gem 'rspec-rails', '~> 1.3.2'

并将以下内容添加到我的规范助手

中

require 'spec/rails'

使用Rails 2.3.8和Bundler运行RSpec测试时，“未初始化的常量”
