Question

我正在尝试安装软件包，例如bower install restangular --save

然后Bower要我选择一个Angular版本：

> Unable to find a suitable version for angular, please choose one:
>     1) angular#1.2.6 which resolved to 1.2.6 and has ang-changeorg, angular-cookies#1.2.6, angular-mocks#1.2.6, angular-resource#1.2.6,
> angular-sanitize#1.2.6, angular-scenario#1.2.6 as dependants
>     2) angular#1.2.17-build.226+sha.b6388b3 which resolved to 1.2.17-build.226+sha.b6388b3 and has angular-animate#1.2.17-build.226+sha.b6388b3 as dependants
>     3) angular#* which resolved to 1.2.18 and has restangular#1.4.0 as dependants
>     4) angular#~1.2.0 which resolved to 1.2.19-build.258+sha.ea653e4 and has angularfire#0.7.1 as dependants
>     5) angular#>= 1.0.8 which resolved to 1.3.0-build.2845+sha.e57ad6a and has angular-ui-router#0.2.10 as dependants
> 
> Prefix the choice with ! to persist it to bower.json

在这些选项中，ang-changeorg是我在本地工作的另一个项目，与我当前的工作目录无关。

我当前项目的bower.json如下：

{
  "name": "ang-changeorg",
  "version": "0.0.0",
  "appPath": "public",
  "dependencies": {
    "angular": "1.2.6",
    "json3": "~3.2.6",
    "es5-shim": "~2.1.0",
    "jquery": "~1.10.2",
    "bootstrap": "~3.0.3",
    "angular-resource": "1.2.6",
    "angular-cookies": "1.2.6",
    "angular-sanitize": "1.2.6",
    "firebase": "~1.0.11",
    "angularfire": "~0.7.1",
    "spin.js": "~2.0.0",
    "angular-ui-router": "~0.2.10",
    "angular-animate": "~1.2.16",
    "ng-file-upload": "~1.4.0"
  },
  "devDependencies": {
    "angular-mocks": "1.2.6",
    "angular-scenario": "1.2.6"
  },
  "resolutions": {
    "angular": "1.2.6"
  }
}

bower cache clean没有解决这个问题。

为什么凉亭列出ang-changeorg作为依赖？关于这些angularjs版本依赖如何工作的清晰度将是非常棒的。

Answer 1

这是因为在你的bower.json中，你的项目名称是ang-changeorg { "name": "ang-changeorg", "version":

该文件中的所有依赖项

"dependencies": { "angular": "1.2.6", "json3": "~3.2.6", "es5-shim": "~2.1.0", "jquery": "~1.10.2", ...

是“名称”：“ang-changeorg”依赖于。因此，ang-changeorg依赖于角度＃1.2.6，因为角度的1.2.6版本在您的凉亭文件中指定： "dependencies": { "angular": "1.2.6",

Answer 2

bower.json文件中列出的每个软件包都有自己的bower.json文件，其中列出了另一组依赖项。

所以，当它说ang-changeorg有angular#1.2.6作为依赖时，那是因为ang-changeorg包中列有angular#1.2.6个bower.json {{1}}档案。

Answer 3

考虑在所有Bower调用中升级到最新的Angular 1.2.18，你有一些混合依赖，很可能Restangular更喜欢最新版本或至少与最新版本匹配（＆＃34; angular-动画＆＃34;：＆＃34; ~1.2.16＆＃34;）。
我不认为你会看到任何重大变化。

为什么Bower说Angular取决于随机事物？
