从 1.60 更新到 1.72 : Failed to precompile intl:extract_to_arb 后，DART 发布失败

Question

昨晚，我不小心将我的 Dart 编辑器和 SDK 版本从 1.60 更新到了 1.72。意外的意思是我不想在开发时改变我的开发环境，但它发生了。之后，当我尝试“发布获取”时，我看到了这一点:

具体来说，它提示两件事:

导入“包:chart/chart.dart”

导入 'package:chrome/chrome_app.dart' 作为 chrome

在我更新 Dart SDK 之前，它们工作得很好。在 Dart 编辑器中，它提示:
URI 的目标不存在

作为 Dart 的新手，我已经进行了详尽的搜索并且没有运气。截止日期快到了，我焦急地寻找解决方案。我在 Mac Book 上开发。但我也有一个 Windows 7 笔记本。他们正在共享 Dropbox 配备的项目文件夹。昨天在此错误发生之前，我将我的 OS X 更新为 Yosemite。在机器更新时，我尝试在 Windows 7 笔记本中为我的项目发布获取和编译 dart2js。它产生了一些错误。所以我删除了我的整个 Dart 文件夹，现在又从 Mac Book 下载了它。我意识到现在 dart 已经更新到 1.7.2。

对此的任何帮助将不胜感激!

在命令行上，运行“pub cache repair”可能会有所帮助。当我更新时，我经常必须这样做。
