Question

在运行扑打医生时，我缺少以下依赖项：

Android toolchain - develop for Android devices (Android SDK 28.0.3)
     Could not determine java version
Android Studio (not installed)

但是我已经在Android Studio上安装了这两种软件并正在开发应用程序。那么为什么flutter找不到这两个？

它也抱怨jre版本。但是Android Studio内部使用已安装的jre。

flutter doctor -v给出以下输出：

Xcode解决方案：

安装Xcode（从https://developer.apple.com/xcode/获取）

确保Xcode应用程序位于/ Applications目录中（不是/ Users / {user} / Applications）。

使用以下命令将xcode-select指向Xcode app Developer目录： sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

注意：确保您的Xcode应用程序路径正确。

Xcode：/Applications/Xcode.app/Contents/Developer Xcode-beta：/Applications/Xcode-beta.app/Contents/Developer

在Mac OS上安装Flutter
