运行“flutter upgrade”后出错

Question

运行后出现以下错误flutter upgrade：

因为来自 sdk 的 flutter_test 的每个版本都依赖于路径 1.5.1 而 flutter_advanced_networkimage >=0.2.9+1 依赖于路径 ^1.6.0，所以来自 sdk 的 flutter_test 与 flutter_advanced_networkimage >=0.2.9+1 不兼容。因此，由于 testapp 依赖于 sdk 中的 flutter_advanced_networkimage ^0.2.10 和 flutter_test any，因此版本求解失败。pub 升级失败 (1)

我的pubspec.yaml：

name: testapp
description: A new Flutter application.

dependencies:
  flutter:
    sdk: flutter
  device_info: "^0.2.0"
  shared_preferences: "^0.4.1"
  flutter_parallax: "^0.1.1"
  cached_network_image: "^0.4.1"
  connectivity: "^0.3.1"
  chewie: "^0.6.0"
  flutter_statusbarcolor: "^0.0.3"
  fluro: "^1.3.1"
  carousel_slider: "^0.0.4"
  flutter_advanced_networkimage: "^0.2.10"
  flutter_sticky_header: "^0.3.0"

dev_dependencies:
  flutter_test:
    sdk: flutter

flutter:
  uses-material-design: true

我正在努力让它工作几个小时，请帮忙

Answer 1

我假设您正在使用测试版渠道。
我认为这不会发生在dev频道中。

切换到dev在命令行 shell 中运行的通道

flutter channel dev 
flutter doctor 

然后再试一次。
