1、进入http://www.scala-sbt.org/download.html

2、

echo"debhttps://dl.bintray.com/sbt/debian/"|sudotee-a/etc/apt/sources.list.d/sbt.list
sudoapt-keyadv--keyserverhkp://keyserver.ubuntu.com:80 --recv2EE0EA64E40A89B84B2DF73499E82A75642AC823
sudoapt-getupdate
sudoapt-getinstallsbt

3、在命令行输入sbt sbt-version，会下载东西，比较慢
