Ruby on rails ActionView:：Template:：错误对象不受支持

我一直在努力寻找这个问题的答案，显然我还没有找到答案。我试着编写了我的第一个小代码，我可以毫无问题地打开服务器，但当我打开它时，服务器告诉我： TypeError:对象不支持此属性或方法 提取的源（第7行附近）：

CTYPE html>
程序101

在我的命令提示中，当出现错误时，它会给出以下信息：

ActionView::Template::Error (TypeError: Object doesn't support this property or method):

提前感谢您

您需要将第6行和第7行中的“应用程序”更改为“默认”

我认为这对理解问题有一些很好的细节。我遇到了确切的问题，并跟踪了堆栈跟踪，似乎原因来自

execjs

。然而，不同之处在于更改

运行时.rb

并不能解决问题。删除

/=require\u树。

确实可以解决问题，但这也不是正确的解决方案，因为它是快速解决方案

---

一个有效的解决方案是安装Node，我认为这可以解决问题。我可以确认这为我解决了问题。我认为这与

runtimes.rb

文件以及Windows上默认的JS env如何糟糕有关。

这显然是错误的。错误会消失，但现在你的应用程序中没有样式表/JavaScript。鉴于错误来自样式表包含行，你能将样式表添加到问题中吗？这不是同一个错误，因此，我怀疑修复是否相同。我不确定这是否是相同的错误，因为我的错误与此相同，即样式表在加载时有问题，但当我从

/=require\u树中删除
/=require\u树时。
从
application.js
中删除时，问题就消失了。快速解决方案是相同的。这是避免问题的另一种方法，而不是实际解决问题。如果你想在你的应用程序中使用JavaScript，不要这样做。好吧，在尝试了更多的东西并澄清之后，我改变了我的答案。请不要投反对票，我尽力了
