Flutter 医生报告说看到了两个 Android Studio 安装

Question

为什么 Flutter 会在同一位置报告有效和无效的 Android Studio 安装？遇到的错误如下：

当我加载 AS 并运行默认应用程序时.. 我在事件日志中得到了这个：

Please run "flutter doctor" to diagnose potential issues

能否请您帮忙解决这个问题，谢谢。

Answer 1

我建议清除 android-studio-dir 和 android-sdk 设置，并让 flutter 自动检测它们的路径：

$ flutter config --android-studio-dir=""
Removing "android-studio-dir" value.

$ flutter config --android-sdk=""
Removing "android-sdk" value.

Answer 2

使用以前版本的 Android Studio 的配置文件删除文件夹解决了我的问题。更新后我有 2 个版本的 Android Studio。

.AndroidStudio3.3 
.AndroidStudio3.4

所以我删除了 3.3(.AndroidStudio3.3) 版本的配置文件，只保留了 3.4(.AndroidStudio3.4) 版本的配置文件

如果您是 Ubuntu 用户并且对 Android Studio 进行了默认安装，则可以在主目录中找到这些文件夹。这些文件夹是隐藏的，因此您必须先取消隐藏它们。

请务必在更新后出现提示时导入以前的设置，否则您将不得不在删除旧配置文件之前重新安装您使用的所有依赖项。

该问题已通过以下两个 flutter 命令解决！...

flutter config --android-sdk /path/to/android/sdk
flutter config --android-studio-dir /path/to/android/studio
