angularjs – Bower为什么说Angular取决于随机事物？

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如下所示：

{
  "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.

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