Question

我有一个Polymer应用程序，配置如下：

我的主要项目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，我有一个聚合物文件夹，其中包含以下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（主要bower.json文件所在的）并且我正在运行bower info polymer bower，则返回以下版本列表：

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控制台返回以下消息并且没有更新到1.6.0但它保持到我当前版本1.2.0：如果找不到合适的聚合物版本，请在下面输入以下数字中选择一个：

    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

没有更新。我应该在聚合物文件夹中手动将版本更改为1.6.0然后运行更新吗？

Answer 1

您需要选择!3这将在名为bower.json的{{1}}中添加一个新对象，其值为resolutions。使用polymer#^1.2.0会在!中保留您的选择。当您选择第一个选项时，它会使用bower.json中的版本设置为使用确切版本，即bower.json。

实际上，您可以在第3个选项之后选择任何内容，因为它们都是1.2.0提到的版本latest above。

使用Bower更新到最新的Polymer
