Scala控制台无法运行

Question

即使我将Java 8设置为默认版本，scala控制台也无法运行。以下是我遇到的错误：

    Exception in thread "main" java.lang.NoClassDefFoundError: javax/script/Compilable
at scala.tools.nsc.interpreter.ILoop.createInterpreter(ILoop.scala:118)

这些是已安装的Java版本：

There are 3 choices for the alternative java (providing/usr/bin/java).
