Question

我正在尝试创建一个包含“Polymer / polymer”和“Polymer / core-elements”的软件包，两者都具有特定版本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polymer版本解析中的冲突：

$ bower install

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

如果我理解正确的话，这就是凉亭的作用：

获取core-elements#0.3.5
认为core-elements#0.3.5取决于core-ajax#>=0.3.0
获取core-ajax <{1}}的最新版本<{1}}
认为core-ajax#0.4.0取决于core-ajax#0.4.0
报告错误，因为我们在polymer#>=0.4.0中为0.3.5指定了确切版本polymer。

确实存在依赖项的有效配置（取bower.json取决于core-ajax#0.3.5），但是bower无法找到此类配置。更糟糕的是，它甚至都没有尝试过。

我做错了吗？如果没有，是否有一些解决方案？

Bower能否正确解析递归依赖？
