我一直在挣扎2天，试图在ace编辑器中扩展突出显示规则。看起来我遵循了教程中的说明，但工具提示（或突出显示规则）似乎没有工作。有人可以告诉我什么是我的代码错误..？它似乎读到'var oop = require（“../ lib/oop”）;'但没有比这更多。什么是requireJS？这似乎是问题...提前谢谢你！Ace编辑器 - 可以请别人告诉我require（）有什么问题？

requireJS是文件/模块加载器，让您在浏览器中使用模块化的代码。我对Ace Editor一无所知，但可能不能使用模块化代码（例如：除非设置了加载程序，否则不能使用'require'从另一个文件加载文件）。 –
我在上面的代码中添加了require.js，但它仍然不起作用。 –
