安装scala test libraryDependencies错误

Question

当我在我的项目中使用Intellij Idea安装scala测试依赖项时，我收到以下错误

libraryDependencies += "org.scalatest" %% "scalatest" % "2.2.6" % "test"

错误：导入SBT项目时出错： ...

我究竟做错了什么？

Answer 1

版本2.2.6与Scala 2.12不兼容，您应该使用latest available version（3.0.1）。

Answer 2

这就是你想要的：

libraryDependencies += "org.scalatest" %% "scalatest" % "2.2.6" % Test

Answer 3

我有同样的问题，这是由于使用较旧的不受支持的版本。你应该使用更新版本的ScalaTest：

libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.4" % "test"
