Question

在Windows计算机上，我正在这里浏览入门教程：https://www.scala-sbt.org/1.x/docs/sbt-by-example.html

我能够启动sbt shell并进行编译，但是使用run命令只是挂起，我被迫按Ctrl-C退出sbt。

直接对JAR文件运行scala也可以按预期运行。

示例输出如下：

这足以满足我的目的。

我可以通过在build.sbt文件中添加一行来解决此问题。添加ThisBuild / scalaVersion：=“ 2.12.8”之后，我能够使用运行命令。按照主要问题中链接的教程进行操作后，我预计不必这样做，但是也许有人可以阐明一下。

使用在简单教程示例上运行的sbt无法执行
