Error running scala console. Module not found
提问by user3116355
I am able to run sample code, which I have saved in sample.scand the results are displaying on Scala console. But I get an error when running the following program, which I saved as the Timeprogram.scalascript:
我能够运行已保存的示例代码，sample.sc结果显示在 Scala 控制台上。但是在运行以下程序时出现错误，我将其保存为Timeprogram.scala脚本：
/**
* Created by sarathrnair on 3/18/15.
*/
println ( "Enter the seconds" )
val totalSeconds=readInt()
val displaySeconds=totalSeconds%60
val totalMinutes=totalSeconds/60
val displayMinutes=totalMinutes%60
val displayHours=totalMinutes/60
val sec=displaySeconds.toString
val min=displayMinutes.toString
val finalString=displayHours+":"+("0"*(2-min.length))+min+":"+("0"*(2-sec.length))+sec
println (finalString)
The error I get is:
我得到的错误是：
Error running scala console. Module is not specified.
运行 Scala 控制台时出错。未指定模块。
Please help me determine the reason behind this error.

If its a .scala file you need to wrap it into an object that extends App like:
如果它是一个 .scala 文件，你需要将它包装成一个扩展 App 的对象，如：
object Timeprogram extends App {
// Your program here
}

The reason for the error mentioned when selecting "Run Scala Console", i.e. -
选择“运行Scala控制台”时提到的错误原因，即-
Error running scala console. Module is not specified.
运行 Scala 控制台时出错。未指定模块。
is that there is no module specified in the Scala Console Run Configuration. Click on the run configuration dropdown and select "Edit Configurations..." There you can specify a module.
是在 Scala 控制台运行配置中没有指定模块。单击运行配置下拉菜单并选择“编辑配置...”在那里您可以指定一个模块。
But this is just if you want to open a REPL shell within IntelliJ. If you just want to run the Scala program do it as in the accepted answer and just select "Run" instead of "Run Scala Console".
但这只是当您想在 IntelliJ 中打开 REPL shell 时。如果您只想运行 Scala 程序，请按照已接受的答案进行操作，只需选择“运行”而不是“运行 Scala 控制台”。

Because you haven't set up the module yet. Open the configurations of the project and set this project as the module.
因为你还没有设置模块。打开工程的配置，将该工程设置为模块。
