求助 dart 在 webstorm 上开发出现的问题

[WayneLyn]

今天搭建好环境在 webstorm 上点击 run 运行的时候提示
Observatory server failed to start after 1 tries。。重试几次后报错
Could not start Observatory HTTP server:
SocketException: Failed host lookup: 'localhost' (OS Error: nodename nor servname provided, or not known, errno = 8)
#0 _NativeSocket.lookup.<anonymous closure> (dart:io/runtime/binsocket_patch.dart:386:9)
#1 _RootZone.runUnary (dart:async/zone.dart:1379:54)
#2 _FutureListener.handleValue (dart:async/future_impl.dart:126:18)
#3 Future._propagateToListeners.handleValueCallback (dart:async/future_impl.dart:639:45)

环境是 dart2.2 webstorm 是最新版。。代码基本没啥东西，就一个 hello world，点 run 的时候我看运行的是 /usr/local/opt/dart/libexec/bin/dart --enable-vm-service:64289 main.dart... 感觉是这个 vm-service 没启动成功，不知道怎么解决啊
