我有一个针对iOS和Android的kotlin-multiplatform项目。 在common模块中使用了Ktor http客户端。
Android应用程序一切正常。 但是在构建iOS库时，我收到以下异常：
> Task :app:compileKotlinIos FAILED
src/commonMain/kotlin/com/ottamotta/mozoli/api/MozoliApiKtor.kt:4:8: error: unresolved reference: io
import io.ktor.client.HttpClient
^
src/commonMain/kotlin/com/ottamotta/mozoli/api/MozoliApiKtor.kt:5:8: error: unresolved reference: io
import io.ktor.client.features.feature
......和其他一些错误提示，指出ktot依赖项没有被解析。
以下是build.gradle文件：

这是来自 common 模块的文件代码，会产生错误：
