Rails应用程序一旦部署到heroku，就不会加载Arbor.js

Question

我们正在构建一个rails应用程序，并使用Arbor.js在rails应用程序的网页上显示节点图，它在本地主机上运行良好，但是当我们部署时，我们会得到以下错误。

Resource interpreted as Script but transferred with MIME type text/html: "http://www.thoughtly.io/users/9/categories". 29:11
Refused to execute script from 'http://www.thoughtly.io/public/assets/arbor.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled. 29:1
arbor.js/web-workers 
Object {integrator: "verlet", repulsion: 1000, stiffness: 30, friction: 40, dt: 0.02…}

Resource interpreted as Script but transferred with MIME type text/html: "http://www.thoughtly.io/users/9/categories". application-7588a131d5b5b403e30855abe426e8c5.js:11681
physics: 
ErrorEvent {error: null, colno: 1, lineno: 1, filename: "http://www.thoughtly.io/public/assets/arbor.js", message: "Uncaught SyntaxError: Unexpected token <"…}

我们需要使用layout.html.erb中的脚本标记，该脚本标记如下所示：

  <script type="application/javascript" src="/public/assets/arbor.js"></script>

我很难让它在Heroku上运行，而且我找不到足够的文档。有什么想法吗？

如果您尝试直接在浏览器中加载http://www.thoughtly.io/public/assets/arbor.js，您将被重定向到http://www.thoughtly.io/。这意味着script标记试图像解析Javascript文件一样解析一个Unexpected token <页面(这会导致Unexpected token <错误。检查控制器中的任何before_filter是否导致重定向。
