Java Scala 3 hello world已导入，运行sbt时出错

我正在尝试开始使用Scala 3

当我遵循以下教程时：。在terminal中，我可以通过以下方式从github提取hello_world项目：

sbt new scala/scala3.g8

只有当我在新创建的hello world目录中运行sbt时，我才会收到错误（见下图）

安装的java jdk和sbt版本： java版本“16.0.1” sbt脚本版本：1.4.9 ***根据问题@Elliot进行编辑 scala-版本： Scala代码运行程序版本2.13.5

有什么建议可以解决这个问题吗

scala-version

的结果是什么？非常相关的问题：scala code runner版本2.13.5据我所知，sbt设置了我希望在项目中运行的scala版本，但可能是错误的obv。使用如下命令升级：cs install scala3编译器或cs install scala3 repl对我帮助不大，我认为您需要sbt 1.5.0或更高版本。问题已解决。使用sbt 1.5.1版，我可以成功地提取github项目：）在我的主目录中有一个奇怪的文件夹，其中包含sbt 1.4.x版本，需要删除它
