Ruby on rails Launchy:：ApplicationNotFoundError:

试图让

save_和\u open_页面

正常工作会出现以下错误：

1) index page my first test
 Failure/Error: save_and_open_page
 Launchy::ApplicationNotFoundError:
   No application found to handle 'C:/Sites/Sublist_v2/tmp/capybara/capybara-201304211638563116158687.html'
 # ./spec/features/comics_page_spec.rb:6:in `block (2 levels) in <top (required)>'

如果我取消对Launchy行的注释，它工作正常，所以我不确定问题出在哪里。。。路径

c://

可能有问题

Gemfile

group :development, :test do
  gem 'spork-rails'
  gem 'rspec-rails'
  gem 'factory_girl_rails'
end

group :test do
  gem 'faker'
  gem 'capybara'
  gem 'launchy'
  gem 'database_cleaner'
  gem 'shoulda-matchers'
end

我是Launchy的作者，刚刚得知这个问题。我通常通过GitHub修复bug，并将此问题放在那里

任何时候当您遇到Launchy问题时，请打开Launchy并进行调试

通过设置环境变量

launchy\u DEBUG=true

，可以启用启动调试。您可以从shell中执行此操作，如果要在应用程序中嵌入launchy，也可以通过ruby代码执行此操作

% export LAUNCHY_DEBUG=true
% launchy http://stackoverflow.com/questions/16137410/launchyapplicationnotfounderror

或者，如果您正在嵌入launchy：

% irb
>> require 'launchy'
>> ENV['LAUNCHY_DEBUG']="true"
>> Launchy.open( "http://stackoverflow.com/questions/16137410/launchyapplicationnotfounderror" )

这是因为文件路径中的驱动器号被错误地确定为uri方案的一部分

您可以通过将/launchy/lib/launchy/applications/browser.rb中的第12行从以下位置更改来临时修复它：

如果File.exist？（uri.path）和uri.scheme.nil？

到

如果File.exist？（uri.path）&&则返回true！方案。包括？（uri.scheme）

我必须做：

fileUri = 'file:///' + outputFile.path

Launchy.open(fileUri)

---

注意“file:”后面的三个斜杠。这是Windows 8上的github-markdown-0.5.5版本。

有趣的是，我可以将错误消息路径复制粘贴到浏览器中并查看页面。我也有同样的问题。我注意到的一件事是，当我复制url并在命令行中使用

launchy C:/Sites/..

运行它时，我会得到相同的错误，但当我将

文件：//

放在

C:

之前时，它会工作。有相同的问题。它以前工作过。不确定错误是否与运行捆绑包更新有关。可能已返回？您安装了哪些版本的capybara和launchy。您是否正在使用旧的软件（例如ruby<1.9.3）？谢谢您的回复。下面是调试输出：请注意刚才的save_和open_页面没有生成任何错误。但是rspec也没有显示页面。@copiousfreetime你能在这个问题上指导我吗，如果launchy找不到任何链接，比如说有输入错误，那么launchy是否有任何方法可以让它搜索“给定的单词或链接”@Abhinay，只是确保我理解你的要求。你想让Launchy告诉你你传递给它的url是否无效，它的哪一部分无效？@copiousfreetime是的，但我正在寻找一些内置函数来帮助它做同样的事情，现在我正在走这条路，我觉得这条路很跛脚，但现在对我来说很好，但是，如果你有任何建议，我愿意尝试。这是代码，解决方案已经过验证，并且有效。请将其标记为答案，以便Brad获得悬赏点数。谢谢

fileUri = 'file:///' + outputFile.path

Launchy.open(fileUri)
