我想安装Scala REPL在windows10. 我在互联网上环顾四周，但我似乎找不到如何获取scala二进制文件和REPL. 这些链接似乎建议我使用Intellij或sbt。如果我得到 sbt，创建项目的方式是例如sbt new hello，它似乎做了很多事情（见下文）！
问题 1 - 我怎样才能得到REPL. 我不想创建项目，我只需要一个命令行工具来练习编写表达式。
问题 2-安装后sbt，我安装了，sbt new hello并且在命令行中看到结果让我不知所措。下面在做什么sbt以及为什么项目仍未创建（请参阅最后的错误，Template not found for: hello？我已截断输出以保持在字数限制内
C:\Users\manuc\Documents\manu>mkdir scala_programs
C:\Users\manuc\Documents\manu>cd scala_programs
C:\Users\manuc\Documents\manu\scala_programs>sbt new hello

接受的答案是错误的
官方页面https://www.scala-lang.org/download/提供了三种开始使用 scala 的方法：下载 Intellij或下载 SBT。
这些选项下面是：安装 Scala 的其他方法。第一个选项是下载适用于 Windows 的 Scala 二进制文件。您可以下载、安装、将其添加到 PATH 中，然后在scala命令行中键入以启动 REPL。
