Getting compilation error when trying to use openzeppelin for erc20 token

Question

I installed Openzeppelin framework and created a simple token sol file.

pragma solidity ^0.4.24;

import "node_modules/openzeppelin-solidity/contracts/token/ERC20/MintableToken.sol";

contract SToken is MintableToken {
    string public constant name = "SS Token";
    string public constant symbol = "SKS";
    uint8 public constant decimals = 2;
}

When I tried compiling i am getting following error.

node_modules/openzeppelin-solidity/contracts/token/ERC20/StandardToken.sol:3:1: ParserError: Source "node_modules/openzeppelin-solidity/contracts/token/ERC20/BasicToken.sol" not found: File import callback not supported import "./BasicToken.sol";

Any idea/thoughts what can be possible reason.

Answer 1

Most probably, you failed to install node modules properly. I tried using Remix online browser and could easily deploy your contract just changing from local node modules to point github repository of zeppelin.

pragma solidity ^0.4.4;

import "github.com/OpenZeppelin/openzeppelin-solidity/contracts/token/ERC20/MintableToken.sol";

contract SToken is MintableToken {
    string public constant name = "SS Token";
    string public constant symbol = "SKS";
    uint8 public constant decimals = 2;
}
