flutter - Android SDK 缺少命令行工具

问题描述

我已经安装了flutter，但是当我运行flutter doctor以验证安装时，我得到：-

Android SDK is missing command line tools

我已经检查了命令行是否已安装。

我需要做什么才能消除此错误？

我在flutter doctor -v下面包含了完整的输出：-

$ flutter doctor -v

解决方案

在 Android Studio 上打开 SDK 管理器。

转到 SDK 工具选项卡。

检查是否选中了 Android SDK 命令行工具。如果没有，请检查并应用更改。

由于某种原因，在更新 Flutter 和 Android Studio 后，我也遇到了这个错误。似乎由于某种原因没有自动安装一些新要求。

这为我修好了。
