Flutter 运行错误:您尚未接受许可协议 [英] Flutter run error : You have not accepted the license agreements

问题描述

我正在使用 Google flutter 开发 android 和 ios 应用.
当我将 shared_preferences 之类的新依赖项添加到 pubspec.yaml 然后在终端中执行 flutter run 时，出现此错误:

I'm developing android and ios app with Google flutter.
when I add a new dependency like shared_preferences to pubspec.yaml and then execute flutter run in terminal, I got this error:

• 出了什么问题:配置项目:shared_preferences"时出现问题.
  您尚未接受以下 SDK 组件的许可协议:[Android SDK Platform 27].

我知道为什么会这样！因为我系统上最新的 Android SDK 平台是 26 .它尝试下载 sdk 27​​，然后失败.没问题！我转到位于此处的库缓存文件夹:

I know why it happens! because the latest Android SDK platform on my system is 26 . it trys to download sdk 27 and then fails. no problem! I go to library cached folder which located here :

C:Users...AppDataRoamingPubCachehostedpub.dartlang.orgshared_preferences-0.3.1android

C:Users...AppDataRoamingPubCachehostedpub.dartlang.orgshared_preferences-0.3.1android

并编辑build.gradle文件并将compileSdkVersion 27更改为compileSdkVersion 26.它有效.
到目前为止，我必须为所有新的依赖项执行此操作，
有什么方法可以为所有依赖项定义一个全局的 build.gradle 文件吗?这样就不需要单独编辑每个 buil.gradle.

and edit build.gradle file and change compileSdkVersion 27 to compileSdkVersion 26. it works.
so far I have to do this for all new dependencies,
Is there any way such as defining a global build.gradle file for all dependencies? so no need to edit each buil.gradles individually.

推荐答案

试试这些:

1. 打开你的终端
2. 输入 flutter doctor --android-licenses
3. 按 y 接受每个许可.

1. Open your terminal
2. type flutter doctor --android-licenses
3. press y to accept every license.
