在sbt下，如果我输入“ console”以启动REPL shell，则会出现以下错误。

[error] stack trace is suppressed; run 'last scalaInstance' for the full output
[error] (scalaInstance) Missing scala-library.jar

Answer 1

尝试 assemblyOption in set: = (assemblyOption in set) .value.copy (includeScala = true)

如果这不能解决问题，则可能是与您已安装的插件的兼容性问题，这意味着您必须删除％HOME％中的插件目录。和％HOME％.ivy2，因为它在本地缓存了一些工件。

如果找不到插件，请尝试删除％HOME％.ivy2并再次运行控制台，因为它将删除缓存的工件。

希望对您有帮助。

您可以尝试在您的sbt版本中更新scala版本吗？例如，

scalaVersion := "2.13.0"

Scala“控制台”命令给出错误“ Missing scala-library.jar”
