android - `flutter doctor`期间 flutter 崩溃

Question

我的设定

macOS Mojave

Xcode 10.3

带有最新SDK和NDK的Android Studio 3.5。

我最近将flutter从1.7.8升级到1.9.1 + hotfix，但立即flutter doctor -v在中间崩溃，提供此Terminal输出。

$ flutter doctor -v

有人看到吗？

Answer 1

首轮:flutter config --clear-features
然后flutter config --no-analytics和flutter update-packages
如果一切正常，则可以很好地运行flutter doctor。
