从1.60更新到1.72后,DART pub失败:无法预编译intl:extract_to_arb

Question

昨晚,我意外地将我的Dart编辑器和SDK版本从1.60升级到1.72.意外地意味着我在开发过程中不想改变我的开发环境,但它确实发生了.在那之后,当我尝试"pub get"时,我看到了这一点:

特别是它抱怨这两件事:

1. import'package:chart/chart.dart'

2. 将'package:chrome/chrome_app.dart'导入为chrome

在我更新Dart SDK之前,它们工作正常.在Dart编辑器中,它抱怨:URI的目标不存在

作为Dart的新手,我做了详尽的搜索,没有运气.截止日期即将到来,我焦急地寻找解决方案.我在Mac Book上开发.但我也有一台Windows 7笔记本电脑.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OS X更新为Yosemite.当机器正在更新时,我试图在Windows 7笔记本中为我的项目发布和编译dart2js.它产生了一些错误.所以我删除了我的整个Dart文件夹,现在从Mac Book再次下载它.我意识到现在dart已经更新到1.7.2.

任何有关这方面的帮助将不胜感激!

在命令行上,运行"pub cache repair"可能会有所帮助.我更新时经常要这样做.
