Android nativescript-firebase插件存在问题

通过运行以下命令，我根据本文创建了一个新的nativescript项目：

tns创建fitApp--appid“…”

cd-fitApp

tns插件添加nativescript插件firebase

tns运行android

并相应地更改了AndroidManifest.xml，并将google-services.json放在上面。但我得到了以下错误：

找不到support-compat.jar（com.android.support:support-compat:28.0.0）。 在以下位置搜索：

这是my package.json：
