我有角度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"
  }
...

我不知道以下输出甚至意味着什么......,它在做什么？
