Answer 1

试试这个- tns platform add android

Answer 2

你试过检查你的package.json了吗？还是尝试执行npm i？或tns install

Answer 3

我想有两点：

1. 似乎您没有遵循NativeScript quick setup安装它，因为它可以全部安装在一起。https://docs.nativescript.org/start/quick-setup
2. 如果存在此模块，则应在package.json中检查：

× Component tns-core-modules is not installed. × Component tns-android is not installed. × Component tns-ios is not installed.

您还可以检查以下操作：npm ls <module-name>，其中<module-name>是检查它的模块。

如果对你有帮助的话请告诉我。
