Describe what the problem is?

Following the hello world example.

use aiken/hash.{Blake2b_224, Hash}
use aiken/list
use aiken/transaction.{ScriptContext}
use aiken/transaction/credential.{VerificationKey}

type Datum {
  owner: Hash<Blake2b_224, VerificationKey>,
}

type Redeemer {
  msg: ByteArray,
}

validator {
  fn spend(datum: Datum, redeemer: Redeemer, context: ScriptContext) -> Bool {
    let must_say_hello = redeemer.msg == "Hello, World!"

    let must_be_signed =
      list.has(context.transaction.extra_signatories, datum.owner)

    must_say_hello && must_be_signed
  }
}

Even tried adding the following manually, to avail

use aiken/bytearray
use aiken/dict
use aiken/pairs

What should be the expected behavior?

the following commands should run without errors aiken check aiken build But i had the following errors

(base) ➜  helloworld aiken check
    Compiling katson95/helloworld 0.0.0 (/Users/<me>/helloworld)
    Compiling aiken-lang/stdlib 1.9.0 (/Users/<me>/helloworld/build/packages/aiken-lang-stdlib)

As mentioned in the compatibility matrix in the stdlib's README, you need to use a version of the compiler equal or higher than 1.0.28 to work with stdlib==1.9.0.

In all likelihood, you are not.

you are right, i was using aiken v1.0.26-alpha+075668b sorry didn't check the matrix. I upgraded to aiken v1.0.31-alpha+unknown and it works now. thanks
