'kotlinx.serialization.json.Json'。检查您的模块类路径是否存在缺失或冲突的依赖项

Question

我试图在我的 KMM 应用程序中使用 kotlinx.serialization 来解析来自网站的 json Http 响应。我尝试了许多在网上找到的解决方案，但都没有解决我的问题。我必须更新到 Android Studio/Kotlin 版本 1.5.20 以消除 Kotlin-datetime 模块中的错误。知道面临新的编译器错误。有人可以帮忙吗？

Kotlin 类：

import com.pagetyler.dailynasa.shared.entity.Defaults
import io.ktor.client.*
import io.ktor.client.features.json.*
import io.ktor.client.features.json.serializer.*
import io.ktor.client.request.*



class NasaPicsApi {
    private val httpClient = HttpClient {
        install(JsonFeature) {
            val json = kotlinx.serialization.json.Json { ignoreUnknownKeys = true }
            serializer = KotlinxSerializer(json)
        }
    }

    suspend fun getPicture(currDate:String): List<NasaPicture> {
        val ep = "$PICTURES_ENDPOINT$EXTENSION?api_key=$DEFAULT_APIKEY;date=$currDate  "
        return httpClient.get(ep)
    }

    companion object {
        private val PICTURES_ENDPOINT = Defaults().PICTURES_ENDPOINT
        private val EXTENSION = Defaults().EXTENSION
        private val DEFAULT_APIKEY = Defaults().DEFAULT_APIKEY
    }
}

这个问题似乎是 Android Studio 4.2.2 Beta 5 独有的问题。我在迁移到它之前没有这个问题。当我迁移到 Artic Fox 2020.3.1 的下一个版本时，问题就消失了。

尽可能避免使用Android Studio 4.2.2 Build #AI-202.7660.26.42.7486908, built on June 23, 2021。
