出了什麼問題？

我正在嘗試將akka-http導入到我的Scala項目中。我使用IntelliJ作爲IDE。以下是我的build.sbt：出了什麼問題？

import sbt._ 

name := "hello" 

version := "1.0" 

scalaVersion := "2.12.1" 

libraryDependencies ++= Seq(
    "com.typesafe.akka" %% "akka-http-experimental" % "1.0", 
    "com.typesafe.akka" %% "akka-http-spray-json-experimental" % "1.0", 
    "com.typesafe.akka" %%"akka-http-testkit-experimental" % "1.0", 
    "org.scalatest" %% "scalatest" % "2.2.5" % "test" 
)

這是我遇到的錯誤：

似乎並不像那些庫可用於斯卡拉2.12：

您正在使用這些庫的過時版本。 Akka HTTP不再是實驗性的，在撰寫本文時，最新版本是10.0.9。更新您的build.sbt：

scalaVersion := "2.12.1" 

libraryDependencies ++= Seq(
    "com.typesafe.akka" %% "akka-http" % "10.0.9", 
    "com.typesafe.akka" %% "akka-http-spray-json" % "10.0.9", 
    "com.typesafe.akka" %%"akka-http-testkit" % "10.0.9", 
    "org.scalatest" %% "scalatest" % "3.0.3" % "test" 
)

注意，對於ScalaTest，你如果你使用Scala的2.12升級到3.x。
