Heroku：rails：“没有这样的文件加载 - URI（LoadError）”

刚开始使用Heroku和rails应用程序，我无法启动rails应用程序。Heroku：rails：“没有这样的文件加载 - URI（LoadError）”

的Ruby版本在Heroku ...

$ Heroku上运行 “红宝石-v”

罪魁祸首似乎如下以上：

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)

很明显，加载“URI”模块存在问题。

问题是缺少的？此外，heroku报道的ruby版本是1.9.3，那么为什么在上面的日志中我看到“1.9.1”。这是问题的一部分吗？

非常感谢！

1.9.1的东西是一个误称 - 所有的红宝石都这样做。 – 2012-08-17 10:31:34

谢谢尼尔，我找到了问题的根源。在我的一个控制器中需要'URI'。评论它帮助解决上述错误......但我确实需要URI，所以仍然在修复中。 – user1535036 2012-08-17 16:49:46

发现问题...

我用的是需要“URI”在我的代码...如果我改变这个要求“URI”它工作在Heroku。

要明确，要求'URI'在我的本地开发环境中工作。

对我来说同样的行为。我需要一个名为'Facebook.rb'的文件，在本地工作得很好，甚至可以在本地运行生产环境中的应用程序;但它在Heroku上不起作用。将所需文件更改为小写字母，即“facebook.rb”，并且一切正常。 – rjgonzo 2012-12-30 18:40:09

据了解，Mac OS X文件系统默认情况下不区分大小写，而Linux文件系统区分大小写。因此，URI和uri在Mac上是相同的，而require 'URI'将在Linux上失败，因为您正在查找的文件被称为uri。

Heroku：rails：“没有这样的文件加载 - URI（LoadError）”
