ArgumentError“interning empty string”Rails
突然开始为我正在进行的项目中的特定控制器的所有操作获取“实习空字符串”。 这工作正常，然后我开始改变一些位，它破了，我现在似乎无法解决它。 我已经将所有代码回滚到我在进行任何更改之前的github版本，但这似乎没有解决问题。
任何帮助将非常感激。
错误：

查看（不太重要，我认为因为代码没有像渲染页面那样）：
Hello World
我已经玩了几个小时了，这个错误似乎在response_to代码之后和动作’end’之前呈现的动作结束时正确。
您在模板目录中有什么？ 看来你的一个模板有一个空的语言环境，导致模板引擎吓坏了。
我认为在Ruby 1.9上允许实习空字符串，但在Ruby 1.8上则不允许。 虽然这对您来说似乎不是问题，但这可以解释为什么错误似乎突然发生。
