我在 Rails 3.2.8 应用程序中包含了arbor-rails gem，它在开发模式下运行良好，但在生产中出现以下错误：

我已经完成了设置environments/并发现当我设置以下内容时development.rb：

config.assets.debug = false

我在开发模式下也遇到错误。当我将其设置为true生产时，它可以正常工作。这可能是什么原因造成的？

更新： 这似乎实际上与arbor.jsarbor_path中的函数有关。

arbor.js 使用Web Worker，这意味着您需要为 Worker 创建提供指向 arbor.js 脚本所在位置的适当链接。

解决此问题的方法是提供 arbor.js 文件的绝对路径，而不是让代码使用 arbor_path 函数，因为缓存逻辑或提供 js 文件的方式可能会搞砸。

换句话说，尝试替换

i=new Worker(arbor_path()+"arbor.js");

和

i=new Worker("/final/path/to/arbor.js");

在 arbor.js 中

正如@Asimov4 所说，问题是在以下调用中产生的：

new Worker(arbor_path()+"arbor.js");

尽管如此，与资产预编译兼容的更优雅的解决方案是将其更改为：

new Worker("<%= asset_path('arbor.js') %>");

注意：记得将 .js 文件更改为 .js.erb！
