Question

我已安装版本： Dart Editor版本1.1.3.release（STABLE） Dart SDK版本1.1.3 我使用聚合物库创建了一个新的Web应用程序。该应用程序是带来编辑器的原始示例：clickcounter。我没有添加或删除任何内容。应用程序正常运行没有错误。但是在尝试编译时，会出现很多错误。我遵循了dartlang.org中给出的建议。因此，不编译带来编辑器的原始示例？有人有线索吗？你可以自己试试。这是OUTPUT中显示的错误列表：

Error: Compilation failed.

我找不到错误。一个想法??

Answer 1

我只是尝试过并且没有任何错误和警告。可能是你的包（依赖项）有问题。您可以尝试pub get和pub upgrade（来自pubspec.yaml上下文菜单）并在显示错误时发布输出。
