Question

我在我的Rails 3.2.8应用程序中包含了arbor-rails gem，它在开发模式下工作正常，但在生产中我收到以下错误：

我已完成environments/中的设置并发现当我在development.rb中设置以下内容时：

config.assets.debug = false

我也在开发模式下得到了错误。当我在生产中将它设置为true时，它可以正常工作。可能导致这种情况的原因是什么？

更新：实际上似乎与arbor.js中的arbor_path功能有关。

Answer 1

arbor.js使用web worker，这意味着您需要为Worker创建提供指向arbor.js脚本所在位置的相应链接。

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，该函数可能会被缓存逻辑或js文件的服务方式弄乱。 / p>

换句话说，尝试替换

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

与

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

arbor.js中的

Answer 2

正如@ Asimov4所述，问题出现在以下电话中：

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：请记住将.js文件更改为.js.erb！

config.assets.debug如何导致我的Rails应用程序崩溃？
