to use the init_if_needed feature, i put in my Cargo.toml:

[dependencies]
anchor-lang = { version = "0.25.0", features = [ "init_if_needed" ] }
anchor-spl = "0.24.2"
mpl-token-metadata = { version = "1.2.5", features = [ "no-entrypoint" ] }

and get anchor build error:

error: failed to select a version for `anchor-lang`.

Hey looks like the dependencies are not correct anchor-lang 0.25 expects also anchor-slp 0.25. Also it should be init-if-needed not init_if_needed try

[dependencies]
anchor-lang = {version = "0.25.0", features = ["init-if-needed"]}
anchor-spl = "0.25.0"
mpl-token-metadata = { version = "1.2.5", features = [ "no-entrypoint" ] }

You can check the correct dependencie here: https://crates.io/crates/anchor-spl/0.25.0/dependencies

  • i guess i stopped where the anchor book said i should uninstall npm and use avm. do they really mean i should entirely remove nodejs from my system? seems wrong.

    all this was because i wanted the init_if_needed feature. are we advised to make the client take responsibility for creating associated token accounts?
