Changed 5 dependencies!
降低角度!!!!!
< angular 0.0.7（was 0.9.10）（15个新版本可用）
< angular 0.0.7 (was 0.9.10) (15 newer versions available)
如果我更改浏览器的依赖关系：
If I change my dependencies for browser:
dependencies:
browser: ">=0.10.0+2 <0.11.0"
结果：

analyzer_experimental 0.8.6
angular 0.0.7 (15 newer versions available)

我使用Dart 1.3 .0！所以 - 这是今天的最新版本。
我不知道pub upgrade在这里做什么，但它不管理依赖...
I'm using Dart 1.3.0!!! so - this is the latest version for today.I don't know what pub upgrade is doing here but it does not manage dependencies...
任何提示？
[更新]
作为解决方法，我将我的依赖项更改为
[Update]
As a workaround I change my dependencies to
dependencies:
polymer_elements:
git: https://github.com/ErikGrimes/polymer_elements
polymer_ui_elements:
git: https://github.com/ErikGrimes/polymer_ui_elements
angular: any
# git: https://github.com/angular/angular.dart
# Incompatible version constraints on html5lib:
# - angular depends on version >=0.9.2 <0.10.0
# - polymer depends on version >=0.10.0 <0.11.0
lawndart: any
validate: any
http_utils: any
直接链接到GitHub几乎解决了一切。
除了Angular !!!!
Directly linking to GitHub solves almost everything.Except Angular!!!!
Resolving dependencies... (50.0s)
< angular 0.0.7 (was 0.9.10) (15 newer versions available)
> barback 0.12.0 (was 0.11.1) (1 newer version available)
cipher 0.6.0 (1 newer version available)
< di 0.0.24 (was 0.0.34) (10 newer versions available)
非常令人沮丧，我花了差不多3小时才得到最新的聚合物版本，而角度仍然是15个版本。
Very frustrating, it took me almost 3h to get the latest polymer version and angular is still 15 versions behind.
推荐答案
是关于类似体验的讨论
Here is a discussion about a similar experiencehttps://groups.google.com/forum/#!searchin/angular-dart/0.0.7/angular-dart/PnvkUudHulg/ZtM3Y8xH_ugJ
我想你应该添加版本约束每个依赖的奇怪的（太旧）版本，直到 pub升级投诉，它不能解决依赖。
I guess you should add version constraints on every dependency where weird (too old) versions are fetched until pub upgrade complaints that it is not able to resolve the dependencies.This could help to find the culprit.
pub deps 命令是在Dart 1.4中添加的显示哪个包取决于其他包。
The pub deps command was added in Dart 1.4 to show which package dependes on which other packages.
