我尝试使用Hilt将天气存储库注入到我的视图模型中，但得到以下错误消息：
WeatherRepository不能在没有@ Provides注解的方法的情况下提供。
公共抽象静态类SingletonC实现WeatherApplication_GeneratedInjector

Weather DAO：

@Dao
interface WeatherDao {
    @Insert(onConflict = OnConflictStrategy.REPLACE)
    suspend fun insertWeatherItem(weatherItem: WeatherItem)
    @Query("DELETE FROM WEATHERITEM WHERE cityName = :cityName")
    suspend fun deleteWeatherItem(cityName: String)
    @Query("SELECT * FROM WEATHERITEM WHERE cityId = :id")
    fun getWeatherItem(id: Int): Flow<WeatherItem>
    @Query("SELECT * FROM WEATHERITEM")
    fun getAllWeatherItems(): Flow<List<WeatherItem>>
}

天气仓库：

class WeatherRepository(private val weatherDao: WeatherDao) {
     suspend fun insertWeatherItem(weatherItem: WeatherItem) = weatherDao.insertWeatherItem(weatherItem)
     suspend fun deleteWeatherItem(cityName: String) = weatherDao.deleteWeatherItem(cityName)
     fun getWeatherItem(id: Int): Flow<WeatherItem> = weatherDao.getWeatherItem(id)
     fun getAllWeatherItems(): Flow<List<WeatherItem>> = weatherDao.getAllWeatherItems()
}

天气数据库：

@Database(entities = [WeatherItem::class] ,version = 1)
abstract class WeatherDatabase :RoomDatabase(){
    abstract fun weatherDao(): WeatherDao
