我正在使用

  • IntelliJ IDEA 126.330
  • Scala 插件 0.7.142
  • JVM 1.6
  • 斯卡拉 2.10
  • 在 Windows 7 x64 下

决定尝试 Scala 并编写以下应用程序

object main {
  def main(args: Array[String]) {
    println("Hello, world!")
  }
}

然后我创建了 Scala 控制台运行配置。当我尝试运行它时，我在控制台中得到以下输出

谷歌搜索后，我发现建议将-usejavacp参数传递给应用程序。它有助于摆脱错误，但应用程序没有被执行。我在控制台中看到的只是

我还尝试在 IDE 选项中禁用 Scala 编译服务器。也没有帮助。

我如何解决它 ？

您应该使用应用程序运行配置类型。Scala 控制台是运行交互式控制台，而不是应用程序。
