ruby-on-rails - Rspec 无法在 ubuntu 上运行

Question

我正在处理一个困扰我很长一段时间的问题。出于某种原因，我无法在本地计算机上启动 rspec。我尝试了多种方法来安装和运行它，但都没有奏效。我使用 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，我将以下条目添加到我的 Gemfile 中:

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

gem list

我看到了

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

所以，它必须在那里。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 spec/model/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

bundle exec spec

我明白了

bundler: command not found: rspec Install missing gem executables with bundle install

好吧，到目前为止还很糟糕。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

Suggested packages: ruby-rspec The following NEW packages will be installed: ruby-rspec-core 0 upgraded, 1 newly installed, 0 to remove and 73 not upgraded.

好的，让我们开始输入

rspec spec/model/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。我想 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来让它发挥作用。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。

有没有人猜到我还能尝试什么？或者我应该改变什么？

出于某种原因，我注意到 Ubuntu 上的环境加载不够早，无法触发捆绑程序加载测试组 gem。我还没有找出根本原因，但像这样运行我的测试是可行的:

RAILS_ENV=test bundle exec rspec
