I get these version import errors when I tried to execute "brownie run scripts/deploy_lottery.py" I'm learning blockchain with the help of freecodecamp.org's youtube video.
it's working fine with the older version.
pragma solidity ^0.4.11;
import "@chainlink/contracts/src/v0.4/ERC677Token.sol";
import {StandardToken as linkStandardToken} from
"@chainlink/contracts/src/v0.4/vendor/StandardToken.sol";
but I'm using this new version,
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.11;
import "@chainlink/contracts/src/v0.8/ERC677Token.sol";
import {StandardToken as linkStandardToken} from
"@chainlink/contracts/src/v0.8/vendor/StandardToken.sol";
contract LinkToken is linkStandardToken, ERC677Token {
uint256 public constant totalSupply = 10**27;
string public constant name = "ChainLink Token";
uint8 public constant decimals = 18;
string public constant symbol = "LINK";
function LinkToken() public {
balances[msg.sender] = totalSupply;
}........
