我从 telegram/bot4s 存储库复制了代码，将部分代码放入“object Main extends App”，创建 sbt 文件，安装库。

import cats.instances.future._
import cats.syntax.functor._
import com.bot4s.telegram.api.RequestHandler
import com.bot4s.telegram.api.declarative.Commands
import com.bot4s.telegram.clients.{FutureSttpClient, ScalajHttpClient}
import com.bot4s.telegram.future.{Polling, TelegramBot}
import com.bot4s.telegram.methods.SendDice

import scala.util.Try
import scala.concurrent.Future

/** Generates random values.
 */


class RandomBot(val token: String) extends TelegramBot
  with Polling
  with Commands[Future] {

  //LoggerConfig.factory = PrintLoggerFactory()
  // set log level, e.g. to TRACE
  //LoggerConfig.level = LogLevel.TRACE

  // Use sttp-based backend
  implicit val backend = SttpBackends.default
  override val client: RequestHandler[Future] = new FutureSttpClient(token)

  // Or just the scalaj-http backend
  // override val client: RequestHandler[Future] = new ScalajHttpClient(token)

  val rng = new scala.util.Random(System.currentTimeMillis())
  onCommand("coin" or "flip") { implicit msg =>
    reply(if (rng.nextBoolean()) "Head!" else "Tail!").void
  }
  onCommand("real" | "double" | "float") { implicit msg =>
    reply(rng.nextDouble().toString).void
  }
  onCommand("/die" | "roll") { implicit msg =>
    reply("⚀⚁⚂⚃⚄⚅" (rng.nextInt(6)).toString).void
  }
  onCommand("random" or "rnd") { implicit msg =>
    withArgs {
      case Seq(Int(n)) if n > 0 =>
        reply(rng.nextInt(n).toString).void
      case _ => reply("Invalid argumentヽ(ಠ_ಠ)ノ").void
    }
  }
  onCommand("choose" | "pick" | "select") { implicit msg =>
    withArgs { args =>
      replyMd(if (args.isEmpty) "No arguments provided." else args(rng.nextInt(args.size))).void
    }
  }

  onCommand("auto") { implicit msg =>
    request(SendDice(msg.chat.id)).void
  }
  // Extractor
  object Int {
    def unapply(s: String): Option[Int] = Try(s.toInt).toOption
  }
}


object Main extends App {
  val bot = new RandomBot("tokenhere")
  val eol = bot.run()
  println("Press [ENTER] to shutdown the bot, it may take a few seconds...")
  scala.io.StdIn.readLine()
  bot.shutdown() // initiate shutdown
  // Wait for the bot end-of-life
  Await.result(eol, Duration.Inf)
}


ThisBuild / version := "0.1.0-SNAPSHOT"

ThisBuild / scalaVersion := "2.13.16"

lazy val root = (project in file("."))
  .settings(
    name := "Meower"
  )

// Core with minimal dependencies, enough to spawn your first bot.
libraryDependencies += "com.bot4s" %% "telegram-core" % "5.8.4"

// Extra goodies: Webhooks, support for games, bindings for actors.
libraryDependencies += "com.bot4s" %% "telegram-akka" % "5.8.4"

但此后我构建失败：

C:\Users\днс\Music\play-samples-3.0.x\Meower\src\main\scala\Main.scala:25:26 未找到：值 SttpBackends 隐式 val backend = SttpBackends.default

C:\Users\днс\Music\play-samples-3.0.x\Meower\src\main\scala\Main.scala:26:49 找不到参数后端的隐式值：sttp.client3.SttpBackend[scala.concurrent.Future,Any] 涉及默认参数的应用程序中发生错误。override val client：RequestHandler[Future] = new FutureSttpClient(token)

C:\Users\днс\Music\play-samples-3.0.x\Meower\src\main\scala\Main.scala:71:3 未找到：值 Await Await.result(eol，Duration.Inf)

C:\Users\днс\Music\play-samples-3.0.x\Meower\src\main\scala\Main.scala:71:21 未找到：值 Duration Await.result(eol，Duration.Inf)

我需要做什么来解决这些问题？

我研究了“找不到 SttpBackends + “涉及默认参数的应用程序中发生错误。”” 并试图修复我的代码，但没有成功……
