Rails的“后卫”无法启动

Question

TDD的新功能，并尝试使用新应用设置环境。 我创建了一个新的Rails应用并捆绑了以下内容：

group :test, :development do
    gem 'turn'
    gem 'rspec-rails'
    gem 'capybara'
    gem 'guard-rspec'
    gem 'growl_notify'
end

在执行rspec：install和guard初始化之后，我尝试运行“ guard”，但得到了（-10660）（Connect :: CantLaunchApplicationError）。 以下是控制台输出：

看起来是grol_notify的问题。

Guard使用的代码路径涉及在OS X上使用LaunchServices ，这要求正在运行的应用程序不在垃圾箱中。 尝试启动垃圾箱中的应用程序时会引发错误kLSAppInTrashErr = -10660 。

在这种情况下，请在回溯中查看此行：

from /Users/Username/.rvm/gems/ruby-1.9.3-p194/gems/growl_notify-0.0.3/lib/growl_notify.rb:29:in `register'

看起来它正在尝试使用Growl（请参阅此处的代码）。 我会检查您的回收站是否完全空了，如果您打算使用growl_notify，请确保已正确安装Growl，否则请禁用它。
