改成 ...AppData\Local\Android\Sdk\Tools\bin\
sdkmanager ... 試試看
如果成功
還是有下一個問題(android-license)要解決
不如用以下這個方法
可以一次滿足兩個願㙜
1.Open Android Studio
2.Tools Menu, SDK Manager
3.In the window that comes up there are inner panels, choose SDK Tools panel
4.Tick Android SDK Command-line Tools
5.Choose Apply button near the bottom of the window
At that point, you will be prompted to accept the SDK license and the command line tools will be installed. Your license issue should now be resolved.
