紅寶石請速錯誤

我試圖安裝this dashing widget，我得到以下錯誤，當我運行dashing start紅寶石請速錯誤

/var/lib/gems/1.9.1/gems/dashing-1.3.1/lib/dashing.rb:26:in `block (2 levels) in <top (required)>': undefined method `history' for Sinatra::Application:Class (NoMethodError)

於是我去掉這個新的小工具（它在/部件目錄文件夾，其工作的各個方面。 rb文件和.erb文件中的代碼）。然而，這個錯誤仍然存在，我不再能夠啓動我的儀表板。這對我來說是個大問題。有人可以幫我嗎？

編輯：

完整的錯誤是

檢查堆棧跟蹤，而不僅僅是這一行，看看它被調用的地方。 – tadman

我已經包含完整的錯誤信息 – user1893354

它看起來像我的psych.rb文件有一個問題 – user1893354

我通過重命名舊的歷史文件

mv history.yml history

，然後重新啓動服務器解決了這個問題。在我的情況下，這是

rackup -p 3030 -s puma

history.yml文件直到我停止服務器後才重新出現。我用納米檢查過，裏面充滿了數據。對不起，我不能說明爲什麼它可能發生。服務器的詳細信息。 Ubuntu 13.10 32位桌面

今天我發現history.yml出現問題的一個可能原因是在Dashing正在運行時關閉一個SSH連接（Windows bluescreened on me，所以這不是我的錯！）。爲了避免啓動守護程序開關 'rackup -p 3030 -s puma -D' ，因爲這會在美洲獅開始啓動後返回提示。當您測試作業時不太有用，但它確實解釋了問題 –
