Heroku：rails：「沒有這樣的文件加載 - URI（LoadError）」

剛開始使用Heroku和rails應用程序，我無法啓動rails應用程序。Heroku：rails：「沒有這樣的文件加載 - URI（LoadError）」

的Ruby版本在Heroku ...

$ Heroku上運行「紅寶石-v」

Running `ruby -v` attached to terminal... up, run.1 
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

$ Heroku的PS

罪魁禍首似乎如下以上：

2012-08-17T10:06:57+00:00 app[web.1]: /app/vendor/bundle/ruby/1.9.1/gems/activesupport-3.2.6/lib/active_support/dependencies.rb:317:in `rescue in depend_on': No such file to load -- URI (LoadError)

很明顯，加載「URI」模塊存在問題。

問題是缺少的？此外，heroku報道的ruby版本是1.9.3，那麼爲什麼在上面的日誌中我看到「1.9.1」。這是問題的一部分嗎？

非常感謝！

1.9.1的東西是一個誤稱 - 所有的紅寶石都這樣做。 – 2012-08-17 10:31:34

謝謝尼爾，我找到了問題的根源。在我的一個控制器中需要'URI'。評論它幫助解決上述錯誤......但我確實需要URI，所以仍然在修復中。 – user1535036 2012-08-17 16:49:46

發現問題...

我用的是需要「URI」在我的代碼...如果我改變這個要求「URI」它工作在Heroku。

要明確，要求'URI'在我的本地開發環境中工作。

對我來說同樣的行爲。我需要一個名爲'Facebook.rb'的文件，在本地工作得很好，甚至可以在本地運行生產環境中的應用程序;但它在Heroku上不起作用。將所需文件更改爲小寫字母，即「facebook.rb」，並且一切正常。 – rjgonzo 2012-12-30 18:40:09

據瞭解，Mac OS X文件系統默認情況下不區分大小寫，而Linux文件系統區分大小寫。因此，URI和uri在Mac上是相同的，而require 'URI'將在Linux上失敗，因爲您正在查找的文件被稱爲uri。
