RequireJS：设置'忽略'的路径 [英] RequireJS: Set path to 'ignore'

问题描述

我正在使用第三方库（通过bower）声明我不想要的依赖项（它只是样式）。是否可以将该依赖项设置为忽略或某些此类值？

I'm using a third-party library (through bower) that declares a dependency that I do not want (it's just styling). Is it possible to set that dependency to 'ignore,' or some such value?

例如：

define(['jquery','dep_i_dont_want'], function(){...});

在require config中：

In require config:

paths: {
    'jquery': 'path/to/jquery',
    'dep_i_dont_want': 'ignore'
}

我只需要查找'dep_i_dont_want'，看看它被忽略了，继续前进而不包含它或失败。这可能吗？我不想编辑第三方JS文件。

I would just require to look up 'dep_i_dont_want', see that it is ignored, and move on without including it or failing. Is this possible? I do not want to edit the third-party JS file.

对于上下文，似乎在'paths'对象中不可能这样：没有未定义，null，''，'忽略'，'空白'等似乎都有效。

For context, it doesn't seem that this is possible in the 'paths' object: none of undefined, null, '', 'ignore', 'blank', etc. seem to work.

我想我可以把它指向一个虚拟模块，但感觉喜欢作弊。

I suppose I could just point it to a dummy module, but that feels like cheating.

是的，这就是你要做的。没有办法告诉RequireJS忽略这个模块。 （对于从CDN加载的模块，您可以为 r.js 提供 empty：方案，但这仅适用于 r.js '在优化期间使用。）

Yes, this is what you have to do. There is no way to tell RequireJS "ignore this module". (There's the empty: scheme that you can give to r.js for modules loaded from CDNs but that's just for r.js' use during optimization.)

您可以做什么而不是设置某种空路径在您调用 require.config 之前添加此模块：

What you can do rather than setting a path to some sort of empty module is add this before your call to require.config:

define('dep_i_dont_want');

这将以这样的方式定义模块：如果在某处需要它，其值将为 undefined 。

This will define the module in such a way that if it is required somewhere, its value will be undefined.
