I am trying Substrate Kitties Workshop

Question

I am trying substrate kitties Workshop. After setting environment and paste the bare-bone code of kitties pallet , when I run cargo build --release the following error occur after 2-3 minutes when building sp-runtime:

error[E0277]: the trait bound `H256: TypeInfo` is not satisfied

error: could not compile `sp-runtime` due to 3 previous errors

Answer 1

This looks an issue with mismatching versions

In your error you complained about sp-runtime:

sp-runtime = { version = "5.0.0", git = "https://github.com/paritytech/substrate.git", tag = "devhub/latest" }

And you can see to sp_core:

sp-core = { version = "5.0.0", git = "https://github.com/paritytech/substrate.git", tag = "devhub/latest" }

I would suggest to delete Cargo.lock and the folder target:

rm -rf target && rm Cargo.lock

And build it again:

cargo build --release

You might need to update more later too, if you have more errors.
