Question

使用grunt-contrib-requirejs任务优化我的require.js项目时，由于相对路径，需要多次脚本多次。以下是构建期间输出的依赖项列表：

components/requirejs/require.js
.tmp/scripts/../../components/flight/lib/././utils.js
.tmp/scripts/../../components/flight/lib/./././utils.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/../../lib/./utils.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/../../lib/registry.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/../../lib/utils.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/debug.js
.tmp/scripts/../../components/flight/lib/././compose.js
.tmp/scripts/../../components/flight/lib/./advice.js
.tmp/scripts/../../components/flight/lib/./utils.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/../../lib/./utils.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/../../lib/registry.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/../../lib/utils.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/debug.js
.tmp/scripts/../../components/flight/lib/./compose.js
.tmp/scripts/../../components/flight/lib/./registry.js
.tmp/scripts/../../components/flight/lib/component.js

注意utils.js包括7次：

.tmp/scripts/../../components/flight/lib/./utils.js
.tmp/scripts/../../components/flight/lib/././utils.js
.tmp/scripts/../../components/flight/lib/./././utils.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/../../lib/utils.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/../../lib/./utils.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/../../lib/utils.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/../../lib/./utils.js

Flight在其utils.js的每个脚本中都需要lib，其路径为./util，有时需要其他依赖项，然后再次需要./util。

grunt-contrib-requirejs将他们的选项直接传递给requirejs，其中包含一个函数trimDots，该函数应该从一个路径段数组中“修剪。和..”。

为什么不照顾一些明显的重复？

如何消除相对路径等于相同绝对路径的其他重复项，我该怎么办？

如果相对路径规范化为绝对路径，那么一切都会很好。

更新

这就是我的项目结构：

.tmp/scripts/ (where coffeescript is compiled)
app/scripts/ (coffeescript source)
components/ (bower components)
dist/ (where optimized code is output)
Gruntfile.coffee (requirejs config)

这是我的Gruntfile中的requirejs配置：

requirejs:
  dist:
    options:
      baseUrl: '.tmp/scripts'
      # paths relative to baseUrl
      paths:
        requireLib: '../../components/requirejs/require'
      include: 'requireLib'
      optimize: 'uglify2'
      generateSourceMaps: true
      preserveLicenseComments: false
      useStrict: true
      wrap: true
      name: 'main'
      out: 'dist/main.js'
      mainConfigFile: '.tmp/scripts/main.js'

以下是app/scripts/main.coffee中的内容：

require.config
  paths:
    # required dependencies
    jquery: '../../components/jquery/jquery'
    es5shim: '../../components/es5-shim/es5-shim'
    es5sham: '../../components/es5-shim/es5-sham'
    # plugins
    text: '../../components/requirejs-text/text'
    pickadate: '../../components/pickadate/source/pickadate.legacy'
  map:
    '*':
      'flight/component': '../../components/flight/lib/component'
  shim:
    '../../components/flight/lib/index':
      deps: ['jquery', 'es5shim', 'es5sham']
    'app':
      deps: ['../../components/flight/lib/index']

require ['app'], (App) ->
  App.initialize()

以下是app/scripts/app.coffee中的内容：

define [
  'ui/apple',
  'ui/orange'
], (Apple, Orange) ->
  initialize = ->
    Apple.attachTo document
    Orange.attachTo document
    return

  initialize: initialize

app/scripts/ui/apple.coffee和app/scripts/ui/orange.coffee都只是：

"use strict"
define ['flight/component'], (defineComponent) ->
  apple = ->
    # stuff
  defineComponent apple

Answer 1

尝试在grunt-contrib-requirejs选项中设置baseUrl：

requirejs: {
    compile: {
        options: {
            baseUrl: "path/to/base"
        }
    }
}

Answer 2

我看到一些代码导致问题。我知道这个问题是在三年前提出的，所以其中一些问题可能不适用于当时。但我去了back in time，并在回答之前查看了3年前的航班代码。

为什么要为grunt插件提供requireLib？您不应该这样做，因为grunt插件应该加载它自己的。结果将是两个需要libs加载，这只是令人困惑。
Shim配置旨在与non-AMD modules only一起使用，但是您要同时填充“app”和“index”，它们都是AMD模块。我希望这会有一些奇怪的行为。

为了修复＃2并使代码更简单，您可以完全删除垫片并简单地映射所有相关的“航班”：

# main.coffee
require.config
  paths:
    # required dependencies
    jquery: '../../components/jquery/jquery'
    es5shim: '../../components/es5-shim/es5-shim'
    es5sham: '../../components/es5-shim/es5-sham'
    # plugins
    text: '../../components/requirejs-text/text'
    pickadate: '../../components/pickadate/source/pickadate.legacy'
  map
    '*':
      'flight': '../../components/flight/lib'

require ['jquery', 'es5shim', 'es5sham'], (App) ->
  require ['app'], (App) ->
    App.initialize()

# app.coffee
define [
  'flight/index',
  'ui/apple',
  'ui/orange'
], (Apple, Orange) ->
  initialize = ->
    Apple.attachTo document
    Orange.attachTo document
    return

  initialize: initialize

我不确定这是否能解决您的问题，所以如果您可以上传一个包含相关代码的小型zip文件，那将会有很大帮助。
