如何解决 Akka 库依赖错误

  • 772

我正在尝试使用 Scala 设置 API，并发现一些在线资源建议akka。我是 Scala 的新手，所以我正在关注一些文档，还查看了https://doc.akka.io/docs/akka/current/typed/actors.html以获取官方文档和版本。我已经在 build.sbt 中进行了该设置，其余库依赖项如下：

libraryDependencies ++= Seq(
  "com.typesafe.akka" %% "akka-actor-typed" % akkaVersion,
)

当我尝试运行 sbt run 时出现错误sbt.librarymanagement.ResolveException: Error downloading com.typesafe.akka:akka-actor-typed_3:2.9.7。我已验证软件包和版本在此处存在： https: //doc.akka.io/docs/akka/current/typed/actors.html。我想知道我的设置或配置是否有误。

任何关于如何解决此问题的帮助都将不胜感激！完整的错误日志如下，供参考：

    正如Akka - Actors 简介中详细介绍的那样（与您分享的链接相同）

    模块信息

    Akka 依赖项可从 Akka 的库存储库获取。要从那里访问它们，您需要配置此存储库的 URL。

    resolvers += "Akka library repository".at("https://repo.akka.io/maven")

    根据build.sbt您分享的配置，缺少该行
