사소한 질문입니다. 계약서를 배포하려면 어떻게해야합니까?내 네트워크에 HelloWorld 계약을 배포 할 수 없습니다. (testrpc)
pragma solidity ^0.4.17;
contract HelloWorld{
function sayHello() internal pure returns(string){
return("Hello 2018!");
}
}
초기 migrations.js : 내가 가지고있는
는 로 정의 간단한 안녕하세요 계약는 HelloWorld.sol 다음
var Migrations = artifacts.require("./Migrations.sol");
var HelloWorld = artifacts.require("./HelloWorld.sol");
module.exports = function(deployer) {
deployer.deploy(Migrations);
deployer.deploy(HelloWorld);
};
그리고를 마지막으로 이후 메신저 사용 송로 버섯, truffle.js :
module.exports = {
networks: {
development: {
host: "localhost",
port: 8545,
network_id: "*" // Match any network id
}
}
};
나는 명령을 실행
truffle compile
truffle migrate
그런 다음 콘솔로 이동 :
truffle console
그리고 난 JS 사용
var hw
HelloWorld.deployed().then(function(deployed){hw=deployed;});
내가 어떻게 올바르게 배포하는
Error: HelloWorld has not been deployed to detected network (network/artifact mismatch) at C:\Users\Kofola\AppData\Roaming\npm\node_modules\truffle\build\cli.bundled.js:317116:17 at at process._tickDomainCallback (internal/process/next_tick.js:228:7)
를 얻을 수를 내 계약과 테스트 에돔?
나는 또한 내 testrpc 서버가 8545에서 실행 중이고 모든 것이 정상적으로 작동한다고 추가해야합니다. (이것 모두는 localhost에서 실행 중입니다.) 네트워크의 ID를 지정하려고했습니다. 명시 적으로 ID를 설정하고 truffle.js에 지정했지만 여전히 작동하지 않습니다. 또한 함수의 가시성을 변경하려고했습니다.
