?$ sdkmanager --install "cmdline-tools;latest"
-bash: sdkmanager: command not found
配置一下环境变量吧
记得执行
$ source ~/.bash_profile
接下来重新执行，又遇到新问题啦~
$ sdkmanager --install "cmdline-tools;latest"

解决方法
?依旧，记得配置环境变量
$ vi ~/.bash_profile
export PATH=$PATH:$ANDROID_HOME/cmdline-tools/latest/bin
?$ source ~/.bash_profile
上面完了还报同样的错，继续解：
据说是java版本问题，删掉高版本，装成java8
brew uninstall --ignore-dependencies java
我的电脑貌似有java8就木有执行重装java8
看下自己的java版本
$ java -version
java version "1.8.0_192"
Java(TM) SE Runtime Environment (build 1.8.0_192-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.192-b12, mixed mode)
继续重新执行
$ sdkmanager --install "cmdline-tools;latest"
$ flutter doctor --android-licenses
接下来还有XCode需要装一下
APPID啥的折腾半天。。装好之后再看看
$ ?flutter doctor

去安装cocoapods，

以上折腾完之后遇到了新问题
$ flutter doctor
会一直处于loading状态
?解决问题时永远遵循最简单解法原则，所以，你可以永远相信重启大法好，没错儿，我重启了一下电脑再试：
差最后一个问题啦~
