如果在使用 import-mapsimport时库不工作，您仍然可以使用 * sprocket * 指令。

<%= javascript_include_tag "do_not_name_me_application" %>

试验项目：

>> require "open-uri"
>> puts URI.open("http://localhost:3000/assets/do_not_name_me_application.js").read
function bye(text) { console.log(text) };
function hi(text) { console.log(text) };

hi("loaded non module");
bye("also loaded");
