使用Bower更新最新的聚合物

Question

我有一个聚合物应用程序，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，我有一个带有以下JSON的聚合物文件夹：

{
  "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，如果我位于根文件夹(主bower.json文件所在的位置)，并且正在运行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，但它停留在当前版本1.2.0:无法找到适合聚合物的版本，请键入以下数字之一：

    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

nothing被更新为。我是否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？

Answer 1

您需要选择!3，这将在bower.json中添加一个名为resolutions的新对象，其值为polymer#^1.2.0。使用!将使您在bower.json中的选择保持不变。当您选择第一个选项时，它从您的bower.json中获取版本，该版本被设置为使用确切的版本，即1.2.0。

实际上，您可以在第三个选项之后选择任何选项，因为它们都是latest above提到的because of '^'版本。
