为什么不凉亭更新角度升级我的角？

Question

我有角1.2.3，我想升级到1.2.7

> cat bower.json 
... 
    "dependencies": { 
    "json3": "~3.2.4", 
    "jquery": "~1.9.1", 
    "es5-shim": "~2.0.8", 
    "toastr": "~2.0.1", 
    "angular-ui-tinymce": "latest", 
    "underscore": "~1.5.2", 
    "underscore.string": "~2.3.3", 
    "angular-ui-utils": "~0.0.4", 
    "angular-dragdrop": "~1.0.5", 
    "angular-cookies": "~1.2.3", 
    "angular-animate": "~1.2.3", 
    "angular-resource": "~1.2.3", 
    "angular": "~1.2.3" 
    }, 
    "devDependencies": { 
    "angular-mocks": "~1.2.3", 
    "bootstrap": "~3.0.1", 
    "font-awesome": "~4.0.3", 
    "angular-bootstrap-affix": "~0.3.0" 
    } 
... 

我不知道下面的输出甚至意味着....，它正在做什么？

没有什么变化？我还在1.2.3上

> bower --version 
1.2.8 

我错过了什么吗？

> bower info angular 
.... shows all versions including 1.2.7 and 1.2.8-builds as well 

Answer 1

我认为这个问题是关于这个

"angular": "~1.2.3" 

https://github.com/isaacs/node-semver/

"Reasonably close to 1.2.3". 

，所以你应该

"angular": "1.2.7" 

UPDATE更改： （它在评论中，但我认为最好指出）

请注意，您无法将软件包名称传递给update命令并仅更新该单个软件包：它仍然会更新它们全部。您可以通过运行bower install来获得最新版本的单个软件包;它只会覆盖你当前拥有的版本

Answer 2

我认为你的依赖阻止你单独更新角度。例如，看看bower_components/angular-route/bower.json。你会看到一个特定版本的角度列为依赖项（“1.2.3”），而不是~ /“合理关闭”说明符“（”〜1.2.3“）。所以你试图更新角度，但是最远的那个凉亭可以采取你的角度是目前的版本，因为你有其他的包，这完全取决于该版本

如果你做bower update然后鲍尔有机会更新所有的包，包括角路由和其他包这些包的更新现在允许bower更新角度，同时满足依赖关系。另外，我认为如果你根据特定的角度版本（你可以看到依赖关系bower list）标识出所有这些包，并将它们作为像bower update angular angular-mocks angular-resource angular-route angular-sanitize...然后鲍尔也可以执行upd吃了。
