使用带有requirejs的whenjs(Using whenjs with requirejs)

 我无法在whenjs中使用requirejs，它在运行站点时会丢失有关丢失文件的404错误。 我按照whenjs自述文件中的说明操作： 
 
 首先，我在项目根目录中运行git submodule add https://github.com/cujojs/when 。 
 
 然后我在app/public/js/main.js “使用包配置你的加载器”： 
 
requirejs.config({
  baseUrl: "js",
  packages: [
    {
      name: "when",
      path: "../../../when",
      main: "when"
    }
  ]
});
 
 这留下以下目录布局： 
 
project-root/
  app/
    public/
      js/
        main.js
        helpers/
          myhelper.js
  when/
 
 需要whenjs的文件（ myhelper.js ）具有： 
 
define(['when'], function(When) {
 
 这会产生错误 
 
 GET http://localhost:4580/js/when/when.js 404 (Not Found) 
 
 我尝试将project-root/when js文件复制到app/public/js/libs/when 
 
project/
  app/
    public/
      js/
        main.js
        helpers/
          myhelper.js
        libs/
          when/
 
 并使用以下代码： 
 
//main.js
requirejs.config({
  baseUrl: "js",
  packages: [
    {
      name: "when",
      path: "libs/when",
      main: "when"
    }
  ]
});

//myhelper.js
define(['when'], function(When) {
 
 产生相同的错误： 
 
 GET http://localhost:4580/js/when/when.js 404 (Not Found) 
 
 似乎myhelper.js中的任何myhelper.js都忽略了packages声明 - 我不确定是否还有其他我应该在那里做的事情？ whenjs指令不说。 
 
 我试过这个： 
 
//main.js
requirejs.config({
  baseUrl: "js",
  packages: [
    {
      name: "when",
      path: "libs/when",
      main: "when"
    }
  ],
  paths: {
    w: "./libs/when"
  }
});

//myhelper.js
define(['w/when'], function(When) {
 
 这不会产生和错误 - 虽然我还没有尝试过使用它的库... 
 
 Requirejs的版本是v2.1.8，我已经阅读了关于包的API说明，但我不是更明智的 。 是什么意思是whenjs指令在这里不起作用？ 我也尝试了其他设置组合，比如组合paths和packages选项，但无济于事。 
 
 这不是Node或仅javascript项目，因此目录的激烈移动不是一种选择。 
 
 任何帮助深表感谢。 

I am unable to use requirejs with whenjs, it gives 404 errors about missing files when running the site. I'm following the instructions in the whenjs README:
 
Firstly, I run git submodule add https://github.com/cujojs/when when in the project root dir.
 
Then I do "Configure your loader with a package" in app/public/js/main.js:
 
requirejs.config({
  baseUrl: "js",
  packages: [
    {
      name: "when",
      path: "../../../when",
      main: "when"
    }
  ]
});
 
This leaves the following directory layout:
 
project-root/
  app/
    public/
      js/
        main.js
        helpers/
          myhelper.js
  when/
 
The file (myhelper.js) that requires whenjs has:
 
define(['when'], function(When) {
 
This produces the error
 
GET http://localhost:4580/js/when/when.js 404 (Not Found)
 
I tried copying the js files from project-root/when into app/public/js/libs/when
 
project/
  app/
    public/
      js/
        main.js
        helpers/
          myhelper.js
        libs/
          when/
 
and using the following code:
 
//main.js
requirejs.config({
  baseUrl: "js",
  packages: [
    {
      name: "when",
      path: "libs/when",
      main: "when"
    }
  ]
});

//myhelper.js
define(['when'], function(When) {
 
Produces the same error:
 
GET http://localhost:4580/js/when/when.js 404 (Not Found)
 
It appears that whatever is in myhelper.js is ignoring the packages declaration - I'm not sure if there's something else I'm supposed to do there? The whenjs instructions don't say to.
 
I tried this:
 
//main.js
requirejs.config({
  baseUrl: "js",
  packages: [
    {
      name: "when",
      path: "libs/when",
      main: "when"
    }
  ],
  paths: {
    w: "./libs/when"
  }
});

//myhelper.js
define(['w/when'], function(When) {
 
This doesn't produce and error - although I haven't tried using the library with it yet…
 
The version of Requirejs is v2.1.8, and I've read the API instructions regarding packages but I'm none the wiser. What is it that means the whenjs instructions don't work here? I've tried other combinations of settings too, like combining the paths and packages options but to no avail.
 
This is not a Node or javascript only project, so a drastic movement of directories is not an option.
 
Any help is much appreciated.
