1.难解决的： ✗ Android license status unknown , 执行命令👇
$ flutter doctor --android-licenses
A newer version of the Android SDK is required. To update, run:
/Users/zhaoyang/Library/Android/sdk/tools/bin/sdkmanager --update
根据上面提示执行命令👇，有报错
$ /Users/zhaoyang/Library/Android/sdk/tools/bin/sdkmanager --update

当brew upgrade cocoapods时，我遇到Error: cocoapods not installed问题，那就安装一遍cocoapods。可能又遇到bad response Not Found 404👉解决ruby源问题
2. 咋使用上sdkmanager命令行, 待解决
$ sdkmanager --list
-bash: sdkmanager: command not found
A: 添加sdk的path到 ~/.bash.profile
