ruby - 无法加载此类文件 -- app.rb (LoadError)

Question

刚刚使用 Capistrano 部署了一个 ruby​​ 应用程序。我很确定我像往常一样做了一切。 Passenger 虽然输出如下:

cannot load such file -- app.rb (LoadError)
  config.ru:1:in `require'
  config.ru:1:in `block in <main>'
  /home/deploy/apps/blog/shared/bundle/ruby/2.0.0/gems/rack-1.5.2/lib/rack/builder.rb:55:in `instance_eval'
  /home/deploy/apps/blog/shared/bundle/ruby/2.0.0/gems/rack-1.5.2/lib/rack/builder.rb:55:in `initialize'

**Application root**

/home/deploy/apps/blog/current

app.rb 实际上就在这个目录下。

在您的 config.ru 中使用以下内容

require "./app"
run Sinatra::Application

是路径问题
