Rspec 无法在 ubuntu 上运行

Question

我正在处理一个困扰我很久的问题。出于某种原因，我无法在本地机器上启动 rspec。我尝试了各种方法来安装和运行它，但都没有奏效。 我正在使用 bundler 在 git 存储库上运行 Ruby on Rails 2.3.5 和 Ruby 1.8.7。

首先，我尝试将 rspec 安装为 gem。为此，我在我的 Gemfile 中添加了以下条目：

group :test do
  gem 'rspec', '=1.3.0'
  gem "rspec-rails", "=1.3.2"
end
...
group :cucumber do
  gem 'rspec', '=1.3.0'
  gem "rspec-rails", "=1.3.2"  
end

当我检查时

宝石清单

我来看看

*** LOCAL GEMS ***
(...)
rspec (1.3.0)
rspec-rails (1.3.2)

所以，它一定在那里。然后我在 /spec/model/bookmark_step.rb 中创建了一个规范文件。但是当我尝试用

运行它时

rspec 规格/模型/bookmark_spec.rb

我明白了

The program 'rspec' is currently not installed.  You can install it by typing:
sudo apt-get install ruby-rspec-core

使用时

捆绑执行规范

我明白了

捆绑器：找不到命令：rspec 使用 bundle install 安装缺少的 gem 可执行文件

好的，到目前为止很糟糕。让我们试试别的。为什么不从 ubuntu 源安装（我正在使用 Ubuntu 12.04）：

sudo apt-get install ruby​​-rspec-core

建议的包： 红宝石-rspec 将安装以下新软件包： ruby-rspec-核心 0 个已升级，1 个新安装，0 个要移除，73 个未升级。

好的，让我们输入

rspec 规格/模型/bookmark_spec.rb

猜猜我得到了什么......

好的，最后一件事可能是版本不匹配。我猜ubuntu为rails 3安装了rspec，而我需要为rails 2.3.5安装rspec。但我已经尝试了很多让它发挥作用。无论如何，我想那是错误的方式，所以我最终停止寻找最后一条错误消息的确切原因。

有人猜我还能尝试什么吗？或者也许我应该改变什么？

Answer 1

出于某种原因，我注意到在 Ubuntu 上加载环境的时间不够早，无法触发捆绑程序加载测试组 gem。我还没有找出根本原因，但是像这样运行我的测试是可行的：

RAILS_ENV=test bundle exec rspec

Answer 2

我们一直在为我们的 rails 2.3.14 应用程序使用以下内容。我想它也应该适用于 2.3.5...

group :development, :test do
  gem "rspec-rails", "1.3.4"
  gem "steak"
  gem "factory_girl", "2.6.4"
  gem "database_cleaner"
end

group :test do
  gem "mocha"
  gem "capybara", "~> 0.3.9"
end
