如何解决Akka库依赖错误

Question

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 新手，所以我正在关注一些文档，并查看 https://doc.akka.io/docs/akka/current/typed/actors.html 获取官方文档和版本。我已经在我的 build.sbt 中进行了该设置，其余的库依赖项如下：

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

。我已验证此处存在软件包和版本：https://doc.akka.io/docs/akka/current/typed/actors.html。我想知道我的设置或配置是否不正确。

任何有关如何解决此问题的帮助将不胜感激！完整的错误日志如下供参考：

Answer 1

正如Akka - Actors 简介中详细介绍的那样（与您共享的链接相同）

模块信息

Akka 依赖项可从 Akka 的库存储库中获取。要在那里访问它们，您需要配置此存储库的 URL。

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

根据您共享的

build.sbt

配置，该行缺失
