scala> ^Z
  • 上面这个异常可能是由于版本不兼容导致，将scala版本换成2.11.8完美解决
lion@king:~/download/tar$ scala
Welcome to Scala 2.11.8 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_161).
Type in expressions for evaluation. Or try :help.

补充：
环境变量的配置

lion@king:/opt/dev-tools$ cat /etc/profile

# scala home
export SCALA_HOME=/opt/dev-tools/scala-2.11.8
export PATH=${SCALA_HOME}/bin:$PATH
