truffle을 이용해서 개발을 진행하려고 하는데

[공식 문서](https://ko.docs.klaytn.com/smart-contract/ide-and-tools/truffle)를 보고  
진행하는데 자꾸 에러메시지가 나옵니다.

어떤 contract를 migrate 하더라도

truffle-config.js 파일은 위와 같으며

```auto
 compilers: {
    solc: {
       version: "0.5.6", // Fetch exact version from solc-bin (default: truffle's version)
       //docker: true, // Use "0.5.1" you've installed locally with docker (default: false)
       settings: { // See the solidity docs for advice about optimization and evmVersion
        optimizer: {
          enabled: false,
          runs: 200
        },
        evmVersion: "constantinople"
       }
    }
  }

 HDWalletProvider(privateKey, "https://kaikas.baobab.klaytn.net:8651/");

```

위의 내용만 baobab 설정값 변경 및 추가하여 공식문서 예제와 동일합니다.  
node.js version 은 v10.24.1 입니다.

안녕하세요, 클레이튼 포럼에 질문을 올려주셔서 감사드립니다.

사용하신 truffle 버전도 알 수 있을까요?

npm install -g를 통해 설치하셨으면 아래 커맨드로 확인하실 수 있습니다.

```auto
$ truffle version

```

혹은 내부 패키지로 설치하셨으면 아래 명령어 실행 부탁드립니다.

```auto
$ ./node_modules/.bin/truffle version

```

제 버전은

Truffle v5.3.4 (core: 5.3.4)
Solidity - 0.5.0 (solc-js)
Node v14.15.5
Web3.js v1.3.5

```

이렇게 쓰고있습니다…

```auto
pragma solidity ^0.5.0;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/token/ERC20/ERC20Detailed.sol";
import "@openzeppelin/contracts/ownership/Ownable.sol";

contract Migrations is ERC20Detailed,ERC20, Ownable{
    constructor() ERC20Detailed('testcoin','tc',18) public {
        _mint(msg.sender, 10000*10**18);
    }
}

```

ERC20으로 토큰을 간단히 만들어만 보려고 하는데 자꾸 에러만 잡고 있으니까 지치네요 ㅠㅠㅠ

아마 Truffle version이 호환되지 않는 것 같습니다.

공식 문서상에서는 v5.0.26까지 지원한다고 적혀있고, 제가 개인적으로 테스트한 버전은 5.1.23입니다. 이런 버전들로 사용해 보시길 부탁드립니다.

추가적으로 [GitHub - klaytn/klaytn-contracts](https://github.com/klaytn/klaytn-contracts) 이 깃헙 코드도 참고 부탁드립니다.

클레이튼에서 트러플로 빌드하는 기본적인 환경이 설정되어 있습니다.

감사합니다.
