This would be an old issue, but the solutions I have seen on this site aren't working. I'm trying to import a contract of OpenZeppelin to my Remix IDE.
import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v2.4.0/contracts/token/ERC721/ERC721Full.sol"; import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v2.4.0/contracts/drafts/Counters.sol";
And it gives me an error:
Unable to import "undefined": TypeError: Failed to fetch
