【问题描述】：

我正在使用

IntelliJ IDEA 126.330
Scala 插件 0.7.142
JVM 1.6
Scala 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

scala> <console>:5: error: object tools is not a member of package scala
  var value: scala.tools.nsc.interpreter.IMain = _
                   ^

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。也没有用。

我该如何解决？

【问题讨论】：

使用Application运行/调试配置，而不是控制台。
@CrazyCoder 是的，App conf 有效。但是 scala 控制台配置是什么？
用于运行 Scala 交互式控制台。
@CrazyCoder，Serge，您能否将您的回复发布为答案，以便我接受？

标签： scala intellij-idea scala-2.10

【解决方案1】：

您应该使用 Application 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。

【解决方案2】：

这应该可以解决您的问题请参阅以下链接 http://eliasbland.wordpress.com/2010/10/20/error-value-tools-is-not-a-member-of-package-scala-when-using-the-scala-console-in-intellij-idea/

【讨论】：

我删除了异常，但我的应用没有执行。
