运行spark-shell 或者scala命令，出现以下错误：

Welcome to Scala version 2.10.6 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_66).Type in expressions to have them evaluated.Type :help for more information.scala> [init] error: error while loading <root>, error in opening zip fileFailed to initialize compiler: object scala.runtime in compiler mirror not found.** Note that as of 2.8 scala does not assume use of the java classpath.** For the old behavior pass -usejavacp to scala, or if using a Settings** object programatically, settings.usejavacp.value = true.
