我尝试运行此拖放API。当我尝试运行dart文件（使用dart编辑器）时，我得到以下错误：

I'm trying to run this drag and drop API. When I try to run the dart file (with the dart editor) I get the following error:

无法启动pub服务或连接到pub 。

我不熟悉dart。

推荐答案

您有另一个服务侦听端口 8080 （有一个开放的问题，使端口 pub服务正在使用可配置）或已经有 pub服务实例运行（我有这种情况， pub服务在DartEditor崩溃后保持运行）。

Either you have another service listening on port 8080 (there is an open issue to make the port pub serve is using configurable) or there is already a pub serve instance running (I had this occassionally, that pub serve kept running after DartEditor crashed).

如果任何 Dart 进程仍然在运行，并杀死所有，如果有的话，然后启动DartEditor并再试一次。

If it is the later, end DartEditor and check in the TaskManger (Windows) if any Dart process is still running and kill all if any, and then start DartEditor and try again.
