I'm trying to compile the week 1 code on plutus playground hosted locally, but I'm getting this error:

 error:
    Not in scope: type constructor or class ‘PaymentPubKeyHash’
   |
57 |     { aSeller   :: !PaymentPubKeyHash
   |   

              ^^^^^^^^^^^^^^^^^

This is the code that originates the compilation error:

data Auction = Auction
    { aSeller   :: !PaymentPubKeyHash
    , aDeadline :: !POSIXTime
    , aMinBid   :: !Integer
    , aCurrency :: !CurrencySymbol
    , aToken    :: !TokenName
    } deriving (P.Show, Generic, ToJSON, FromJSON, ToSchema)

I have followed the steps on the week1 videos, but I'm getting this error, any help is welcomed. Thank you.

  • What gitrev of plutus-apps are you using? Can you gist your entire code file? I'm guessing either a version mismatch or a typo. Jan 17, 2022 at 2:12

    @SamuelLeathers I just got it working. I ran cabal update in the week1 code folder and the code compiled. Thank you. Jan 17, 2022 at 2:22
  • Also, I was running the plutus playground on a old version of plutus repository not plutus-apps Jan 17, 2022 at 2:24
