运行茉莉花规范时没有收到任何数据

Question

当我运行bundle exec rake jasmine然后浏览到http://localhost:8888/时，我会看到以下错误消息：

No data received
Unable to load the web page because the server sent no data.
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

在控制台里，我看到：

我的Gem版本如下(我已经列出了我认为相关的内容；如果您需要完整的列表，请告诉我)：

(0.1.1)

• coffee-rails (3.1.1)

• coffee-script (2.2.0)

• coffee-script-source (1.2.0)

• jasmine (1.1.2)

• jasmine-core (1.1.0)

• jasmine-headless-webkit (0.9.0.rc1 4f11cba)

• jasmine-rails (0.0.2)

H123< )(1.0.6)

• rails (3.1.0)

• rake (0.9.2.2)

• sprockets (2.0.3)

• therubyracer (0.9.9)

我在Linux 12上运行Chrome 16.0.912.77，通过RVM使用Ruby1.9.2-P290。

这个设置通过茉莉花无头webkit运行得很好：

Running Jasmine specs...
............................
PASS: 28 tests, 0 failures, 0.076 secs.

也许我在jasmine.yml中做了一些不受茉莉花支持的事情？

Answer 1

使用最新的源代码。感谢@avaynshtok指出问题&发送拉请求！

 gem 'railroady', :git => "git://github.com/preston/railroady.git"

Answer 2

这看起来像是铁轨上的窃听器。当我将它添加到我的Gemfile并运行jasmine时，我会看到与您完全相同的错误。茉莉花工作良好的w/o铁路安装。

问题是，在默认范围内，railroady在tasks/railroady.rake中定义了一个tasks/railroady.rake函数。

def format
  @@DIAGRAM_FORMAT ||= 'svg'
end

这就是format，它最终导致调用而不是Kernel.format，从而导致了我们正在看到的异常。

把铁轨拆了看看茉莉花有没有用。
