Flutter 在“顫動醫生”期間崩潰

Question

我的設置

• macOS 莫哈韋
• Xcode 10.3
• Android Studio 3.5，帶有最新的 SDK 和 NDK。

我最近將 flutter 從 1.7.8 升級到 1.9.1+hotfix，但是立即的flutter doctor -v在中間崩潰，給這個終端 output。

$ flutter doctor -v
[✓] Flutter (Channel stable, v1.9.1+hotfix.2, on Mac OS X 10.14.6 18G95, locale en-CA)
    • Flutter version 1.9.1+hotfix.2 at /Applications/Android/flutter
    • Framework revision 2d2a1ffec9 (8 days ago), 2019-09-06 18:39:49 -0700
    • Engine revision b863200c37
    • Dart version 2.5.0

⣽Unhandled exception:
Bad state: Future already completed
#0      _AsyncCompleter.complete (dart:async/future_impl.dart:39:31)
#1      _NativeSocket.startConnect.<anonymous closure>.connectNext.<anonymous closure> (dart:io-patch/socket_patch.dart:523:23)

#5      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:172:12)

有人看到這個嗎？

Answer 1

第一次運行： flutter config --clear-features

然后flutter config --no-analytics和flutter update-packages

如果一切正常，您可以很好地運行flutter doctor 。

Answer 2

首先，您應該始終運行 flutter 命令以避免在運行 flutter 醫生命令時返回錯誤。 有同樣的問題，當我這樣做時，它工作得很好。
