</androidx.constraintlayout.widget.ConstraintLayout>

它看起来像那样 当我展示小吃店时，它看起来像这样 谷歌说小吃店应该显示在底部应用栏和工厂上方，但我不能在尝试显示带有底部边距的小吃店时

val snackbarView = snackbar.view
    val params = snackbarView.layoutParams …

我想编译并启动。

package korat

import tensorflow.TF_Version

fun main(args: Array<String>) {
    print(TF_Version())
}

当我运行命令时：

kotlinc-native /home/fnasibov/IdeaProjects/Korat/src/linuxMain/kotlin/korat/Test.kt -l tensorflow

它返回一个错误：

error: could not find 'main' in '<root>' package.

我怎样才能解决这个问题？

更新 1

添加后-e korat.main 有错误
