Polymer Bower能否正确解析递归依赖关系？

我试图创建一个包含“聚合物/聚合物”和“聚合物/核心元素”的包，这两个包都有特定的版本0.3.5

$ cat bower.json 
{
  "name": "bower-test",
  "private": true,
  "dependencies": {
    "polymer": "Polymer/polymer#0.3.5",
    "core-elements": "Polymer/core-elements#0.3.5"
  },
  "ignore": [
    "**/.*",
    "node_modules",
    "bower_components",
    "test",
    "tests"
  ]
}

$ bower --version
1.3.10

当我尝试安装依赖项时，bower报告了

polymer

版本解析中的冲突：

Unable to find a suitable version for polymer, please choose one:
    1) polymer#>=0.3.0 <1.0.0 which resolved to 0.3.5 and is required by core-elements#0.3.5, core-layout#0.3.5 
    2) polymer#0.3.5 which resolved to 0.3.5 and is required by bower-test 
    3) polymer#>=0.4.0 <1.0.0 which resolved to 0.4.0 and is required by core-ajax#0.4.0, core-animated-pages#0.4.0, core-animation#0.4.0, core-collapse#0.4.0, core-component-page#0.4.0, core-dropdown#0.4.0, core-field#0.4.0, core-header-panel#0.4.0, core-icons#0.4.0, core-iconset#0.4.0, core-iconset-svg#0.4.0, core-input#0.4.0, core-layout-grid#0.4.0, core-layout-trbl#0.4.0, core-list#0.4.0, core-localstorage#0.4.0, core-media-query#0.4.0, core-menu-button#0.4.0, core-meta#0.4.0, core-overlay#0.4.0, core-popup-menu#0.4.0, core-range#0.4.0, core-selection#0.4.0, core-selector#0.4.0, core-shared-lib#0.4.0, core-signals#0.4.0, core-splitter#0.4.0, core-style#0.4.0, core-tooltip#0.4.0, core-transition#0.4.0, marked-element#0.4.0, prettify-element#0.4.0

获取

核心ajax

的最新版本，即

核心ajax#0.4.0

看到

核心ajax#0.4.0

依赖于

polymer#>=0.4.0

报告错误，因为我们在

bower.json

中为

polymer

指定了确切版本

0.3.5

依赖项的有效配置确实存在（以

核心ajax#0.3.5

为例，这取决于

polymer#>=0.3.5

），但是bower无法找到此类配置。更糟糕的是，它甚至没有尝试

我做错什么了吗？如果没有，有什么解决办法吗

一般来说，如果Bower不知道如何解析资源的版本，它会这样提示您。在本例中，它之所以会提示您，是因为您在bower.json中选择了准确的版本

#0.3.5

。如果你放松了我自己解决的一些问题（例如，

=0.3.5@ebidel），我的项目中有几个聚合物用户（只有聚合物本身，不包括任何组件），项目中使用的聚合物的当前版本是
0.3.5
。这就是为什么我不能轻松地将聚合物更新到更高版本的原因（特别是下一个主要版本）。bower.json的依赖项部分现在只包含一行：
“polymer”：“polymer/polymer#0.3.5”
。我想将聚合物组件带到项目中，因此我将
聚合物/核心元素#0.3.5
添加到依赖项列表中，希望这会起作用。我们已脱机同步。对于其他所有人来说，似乎没有一个好方法可以做到这一点。
