無法使Rails 3.2服務器運行

Question

我正在嘗試運行this app，該服務器上一次提交時間大約在一年前。花了一段時間試圖讓所有的寶石和寶石依賴項安裝（包括註釋掉寶石），我可以得到綠燈「捆綁完成」的消息。然而，正在運行的服務器的時候，我碰到下面的錯誤日誌：

是舊的Rails 2.3的插件扔我了嗎？這是我在Hartl的Rails教程之後的第一個「真實世界」項目，很不幸，我沒有很多處理這類錯誤的經驗。該應用程序的Gemfile名爲smartr，其格式爲linked。謝謝！！

Answer 1

Here是一篇文章可以幫助您經營舊appllications溫特的Rails 4.請仔細閱讀這部分沒有更多的供應商/插件，它介紹如何解決你的一個問題。

有關sass-plugin的第二個問題可以通過在development.rb中註釋26字符串來解決。它必須寫在Rails 3應用程序的其他地方。

Answer 2

當我在供應商文件夾中有一些2.x插件時，我得到了類似的錯誤。我刪除它們後，錯誤消失了。

Answer 3

Sass在gemfile中，但它的版本不受限制。由於該項目一年未修改，因此該項目可能會期望舊版Sass。你應該嘗試研究在Gemfile中降級sass並且做bundle update看看會發生什麼。另外，Rails 3.2並沒有在一年前，所以我不會在Rails 3.2上運行這個應用程序。

Answer 4

它看起來像一個名爲Sass :: Plugin的東西是丟失或不正確加載您的應用程序。

檢查，如果上述插件存在
