scala - Cannot compile simple Argonaut expression? -

-

is scalaz , argonaut incompatibility issue or else?

scala> import argonaut._ import argonaut._  scala> import argonaut._ import argonaut._  scala> import scalaz._ import scalaz._  scala> import scalaz._ import scalaz._  scala> val jsonstring: json = jstring("json!") java.lang.incompatibleclasschangeerror: found class scalaz.memo, interface expected   @ argonaut.prettyparams.<init>(prettyparams.scala:112)   @ argonaut.prettyparamss$class.$init$(prettyparams.scala:252)   @ argonaut.argonaut$.<init>(argonaut.scala:3)   @ argonaut.argonaut$.<clinit>(argonaut.scala)   ... 43 elided

build.sbt

  "io.argonaut" %% "argonaut" % "6.1",   "org.scalaz" %% "scalaz-core" % "7.2.4",

currently seems compatible scalaz 7.1.1.
