Unable to import spray in scala.

As the sample code used a library called spray, I tried using the interpreter and got the following error:

Scala itself has only just started recently, and I don't know how to deal with these cases.
I thought it might be necessary to install something like a gem in ruby, but
I was looking into how to do it, but I didn't know...

scala>import spray.json.JsValue
:7:error:not found:value spray
       import spray.json.JsValue

Could someone please tell me?

Or is it impossible to import an interpreter in the first place?

Thank you for your cooperation.
