Use of undeclared type or module near_blockchain

I am getting the following error when trying to compile NEAR smart contracts, but only when compiling to wasm target

   Compiling nep9000 v0.1.0 (/Users/mikkoohtamaa/code/advanced-fungible-token/contract)
error[E0433]: failed to resolve: use of undeclared type or module `near_blockchain`
   --> src/token.rs:144:1
    |
144 | #[near_bindgen]
    | ^^^^^^^^^^^^^^^ use of undeclared type or module `near_blockchain```

Normal cargo build is ok.

Solution

  • Looks like you need to declare #[near_bindgen] on both struct and impl of the contract, impl only is not enough.

    #[near_bindgen]
#[derive(BorshDeserialize, BorshSerialize)]
pub struct Token {
   ...
}


#[near_bindgen]
impl Token {

   ...
}
