rails g scaffold主主体：文本

运行了一个简单的scaffold并出现以下错误：

我不知道如何解决这个问题，所以在正确的方向上找一个点就好了也许我需要正确的gem for exec.js来运行ruby 1.8.7

该版本的exec js需要ruby 1.9或更高版本，因为它使用了新的哈希语法。你必须降级execjs，或者升级你的Ruby

---

自从Ruby 1.8.7差不多一年前问世以来，正确的答案应该是升级Ruby。

我将exec js降级为2.0.0，但运行不正常，谢谢Meagar！我不得不使用'execjs'而不是'execjs'@GregKrsak，这很好，但这与问题中描述的问题无关。这就是为什么我在你的答案中添加is作为注释——以防有人（我）尝试了你的建议，但效果不太好，我可以展示什么对我有效。
