使用 Bower 更新到最新的 Polymer

Question

我有一个配置如下的 Polymer 应用程序：

我的主项目bower.json文件:

{
  "name": "Raf",
  "authors": [
    "Raffaeu <raffaeu@gmail.com>"
  ],
  "description": "Test Project",
  "dependencies": {
    "polymer": "Polymer/polymer#1.2.0",
    "iron-elements": "PolymerElements/iron-elements#^1.0.8",
    "paper-elements": "PolymerElements/paper-elements#^1.0.7"
  }
}

在我的 bower_components 文件夹中，我确实有一个 polymer 文件夹，其中包含以下内容 JSON:

{
  "name": "polymer",
  "version": "1.2.0",
  "main": [
    "polymer.html"
  ],
  "repository": {
    "type": "git",
    "url": "https://github.com/Polymer/polymer.git"
  },
  "dependencies": {
    "webcomponentsjs": "^0.7.2"
  }
}

现在，如果我在根文件夹中（主 bower.json 文件所在的位置）并且我运行正在 bower info polymer bower returns 我的版本列表如下：

bower cached        https://github.com/Polymer/polymer.git#1.6.0
bower validate      1.6.0 against https://github.com/Polymer/polymer.git#*

{
  name: 'polymer',
  version: '1.6.0',
   ...

但是如果我运行 bower update polymer --save 控制台 returns 以下消息并没有更新到 1.6.0 但它仍然是我当前的版本 1.2.0：无法找到适合聚合物的版本，请输入以下数字之一选择一个：

    1) polymer#1.2.0 which resolved to 1.2.0 and is required by MyTestProject
    2) polymer#~1.2.0 which resolved to 1.2.4 and is required by paper-datatable#0.9.8
    3) polymer#^1.2.0 which resolved to 1.6.0 and is required by iron-behaviors#1.0.13
    4) polymer#^1.2.1 which resolved to 1.6.0 and is required by paper-behaviors#1.0.11
    5) polymer#^1.2.4 which resolved to 1.6.0 and is required by iron-menu-behavior#1.1.3
    6) polymer#^1.1.1 which resolved to 1.6.0 and is required by vaadin-grid#1.0.0
    7) polymer#^1.0.0 which resolved to 1.6.0 and is required by iron-a11y-keys-behavior#1.1.1
    8) polymer#^1.1.0 which resolved to 1.6.0 and is required by paper-dropdown-menu#1.1.3

Prefix the choice with ! to persist it to bower.json

? Answer 1

并且没有任何更新。我是否应该在 polymer 文件夹中手动将版本更改为 1.6.0 然后运行更新？

Answer 1

您需要 select !3 这将在您的 bower.json 中添加一个名为 resolutions 的新对象，其值为 polymer#^1.2.0。使用 ! 将在 bower.json 中保留您的选择。因为你是 selecting 第一个选项，所以它从你的 bower.json 中获取版本，该版本设置为使用确切的版本，即 1.2.0.

实际上，您可以 select 第三个选项之后的任何内容，因为它们都是 latest above 提到的版本 because of '^'。
