没有找到类的定义：'yodgorbek.komilov.musobaqayangiliklari.repository.BBCRepository' 和限定符：'bbcModules'。检查你的定义？

我正在开发新闻 android 应用程序并且我已经实现了 Koin 模块，但是我得到了以下异常

在我实现 BBCSportViewModel 逻辑的 bbcModules.kt 下方

val bbcModules = module {
    factory(named("bbcModules")) { (BBCRepositoryImpl(bbcsportNewsApi = get())) }
    // Tells Koin how to create an instance of BBCRepository

    viewModel { BBCSportViewModel(bbcRepository = get(named("bbcModules")))

    }


}

在 BBCRepository.kt 下方

interface BBCRepository {
    // Suspend is used to await the result from Deferred
    suspend fun getBBCList(): UseCaseResult<List<Article>>
}


@Suppress("UNCHECKED_CAST")
class BBCRepositoryImpl(private val bbcsportNewsApi: SportNewsInterface) : BBCRepository {
    override suspend fun getBBCList(): UseCaseResult<List<Article>> {

        return try {
            val result = bbcsportNewsApi.getBBCSport().body()!!.articles
            UseCaseResult.Success(result)
        } catch (ex: Exception) {
            UseCaseResult.Error(ex)
        }
    }
}

我想知道我到底在哪里犯了错误我必须解决的异常我遵循了许多 StackOverflow 的答案它并没有解决我的问题

堆栈跟踪显示未找到 BBCRepository 的定义。

在您的 koin 模块中，您的工厂是 BBCRepositoryImpl 而不是 BBCRepository：

factory(named("bbcModules")) {
   (BBCRepositoryImpl(bbcsportNewsApi = get())) 
}

为了让它工作，你应该确保你提供的接口是 koin：

factory<BBCRepository>(named("bbcModules")) { 
    BBCRepositoryImpl(bbcsportNewsApi = get())
}

或

factory(named("bbcModules")) {
 (BBCRepositoryImpl(bbcsportNewsApi = get())) as BBCRepository 
}
