“QueryMsg”未实现特征“QueryResponses”

Question

我正在尝试编译一个合约，但 schema.rs 有此错误。 我试图使用 Cargo build --release --target wasm32-unknown-unknown 来编译代码。 我们正在尝试使用 cosm wasm 创建多重签名合约。我正在关注 cosmwasm 学院的教程。代码很好。但尝试这个，我很沮丧。请帮忙。如果可能的话，请检查您的不和谐之处。

error: can't compile schema generator for the `wasm32` arch

error\[E0277\]: the trait bound `QueryMsg: QueryResponses` is not satisfied
\--\> src/bin/schema.rs:5:5

7 | |         execute: ExecuteMsg,

| |\____\_^ the trait `QueryResponses` is not implemented for `QueryMsg`

= note: this error originates in the macro `write_api` (in Nightly builds, run with -Z macro-backtrace for more info)

schema.rs

fn main() {
write_api! {
instantiate: InstantiateMsg,
execute: ExecuteMsg,
query: QueryMsg,
}
}

msg.rs

use cosmwasm_schema::{cw_serde, QueryResponses};
use cosmwasm_std::{Addr, Coin};

#[cw_serde]
pub struct InstantiateMsg {
    pub minimum_approvals: i32,
    pub signers: Vec<Addr>,
}

#[cw_serde]
pub enum ExecuteMsg {
    Approve {},
    Revoke {},
    Execute { to: Addr, funds: Coin },
}

#[cw_serde]
#[derive(QueryResponses)]
pub enum QueryMsg {
    // GetCount returns the current count as a json-encoded number
    #[returns(Valueresp)]
    GetCurrentSignatures {},
}


#[cw_serde]
pub struct Valueresp {
    pub count: i32,
}

您必须在提供

--lib

标志的情况下运行命令，它应该可以工作。
