首次启动终端时总是出现此错误。

您好，我在 kotlin 中类序列化时遇到问题

构建.gradl.kt

...
plugins {
    application
    kotlin("jvm") version "1.6.21"
    kotlin("plugin.serialization").version("1.6.21")
}
...
depenedancies{
...
    implementation("io.ktor:ktor-server-content-negotiation:$ktor_version")
    implementation("io.ktor:ktor-serialization-kotlinx-json:$ktor_version")
} 

响应.kt

import kotlinx.serialization.*
...
interface BaseResponse<T>

@Serializable
data class PaginatedResponse<T>(
    val prev: Int?,
    val next: Int?,
    val totalCount: Int = 0,
    val totalPages: Int = 0,
    val data: T? = null,
    val message: String? = null
) : BaseResponse<T>

用法

...
  return PaginatedResponse<List<User>>(
                prev,
                next,
                totalCount,
                totalPages,
                users
            )

我传递的数据看起来很健康 接下来是返回时抛出的错误

kotlinx.serialization.SerializationException: Serializer for class 'PaginatedResponse' is not found.

我尝试将react-native版本更新到最新的0.72.3并运行pod install，这导致了下一个错误

[!] CocoaPods could not find compatible versions for pod "SocketRocket":
  In snapshot (Podfile.lock):
    SocketRocket (= 0.6.0, ~> 0.6.0)

  In Podfile:
    React-Core/RCTWebSocket (from `../node_modules/react-native/`) was resolved to 0.72.3, which depends on
      SocketRocket (= 0.6.1)

Specs satisfying the `SocketRocket (= 0.6.0, ~> 0.6.0), SocketRocket (= 0.6.1)` dependency were found, but they required a higher minimum deployment target.

可能是什么问题？有正常的解决方法吗？

我正在使用 Kotests 为 Ktor 应用程序编写测试，但偶然发现了如何在全局范围内更改测试的环境变量的问题。我尝试过添加withEnvironment，但它给我带来了非常奇怪的错误

我有一个问题，如何在 kotlin 中使用箭头验证超过 10 个值。

fun CreateEventDTO.validate(): Validated<IncorrectInput, CreateEventDTO> =
  name.isEventNameValid()
    .zip(
      about.isAboutValid(),
      phone.isPhoneValid(),
