我在jitpack中得到这个错误,我已经在互联网上尝试了一切。以下是我的错误

Failed to install the following Android SDK packages as some licences have not been accepted.
     platforms;android-26 Android SDK Platform 26
     build-tools;28.0.3 Android SDK Build-Tools 28.0.3
  To build this project, accept the SDK license agreements and install the missing components using the Android Studio SDK Manager.

当我运行。/sdkmanager——licenses

 All SDK package licenses accepted.======] 100% Computing updates...             

使用sudo和上面的命令得到

附加错误日志

我不知道为什么它检查许可证,当我的sdk位置是其他


当前回答

我刚刚做了文件->无效缓存和重新启动 然后安装缺少的包。 为我工作。

其他回答

在28.0.3版本使用带有构建工具的android-28;或者版本26.0.3的构建工具。

或者试试这个:yes | sudo sdkmanager—licenses

在Android Studio去:工具> SDK管理器> SDK工具

在右下方,选中“Show Package Details”框,下载你需要的sdk版本:

目前看来是一个bug: https://issuetracker.google.com/issues/123054726

对我有效的解决方案:

创建一个.travis。Yml文件在你的项目目录,并复制这些行:

before_script:
- mkdir "$ANDROID_HOME/licenses" || true
- echo "24333f8a63b6825ea9c5514f83c2829b004d1fee" > "$ANDROID_HOME/licenses/android-sdk-license"

如果您正在使用颤振,请执行以下步骤

1.open the command prompt

然后执行以下命令

2.C:\Users\niroshan>flutter doctor

您将看到如下问题

实际上,您必须运行下面的命令

C:\Users\niroshan>flutter doctor --android-licenses

在我的情况下,更新buildToolsVersion在应用程序级别构建。Gradle工作得很完美。如果你不知道使用哪个,你可以创建一个新的项目,并复制buildToolsVersion到现有的一个。
