【问题描述】:
我正在尝试编译(通过 Hardhat)一个合同,该合同导入了多个具有不同 Solidity 版本的接口,但我收到以下错误:
Error HH606: The project cannot be compiled, see reasons below.
These files and its dependencies cannot be compiled with your config. This can happen because they have incompatible Solidity pragmas, or don't match any of your configured Solidity compilers.
* contracts/FlashLoaner.sol
Flashloaner.sol:
pragma solidity >=0.5.0 <=0.8.0;
import '@uniswap/v2-periphery/contracts/interfaces/IWETH.sol';
import "@openzeppelin/contracts/token/ERC20/IERC20.sol";
import '@aave/protocol-v2/contracts/interfaces/ILendingPool.sol'; //---> Issue
import "hardhat/console.sol";
contract FlashLoaner {
struct MyCustomData {
address token;
uint256 repayAmount;
}
address public logicContract;
function execute(address _weth, address _contract) external view {
console.log(_weth);
}
}
问题在于@aave/protocol-v2/contracts/interfaces/ILendingPool.sol。如果我将其注释掉,我的合同就会编译得很好。
IlendingPool.sol:pragma solidity 0.6.12;
IERC20.sol:pragma solidity ^0.5.0;
IWETH.sol:pragma solidity >=0.5.0;
Hardhat.config:
module.exports = {
solidity: {
compilers: [
{
version: "0.5.7"
},
{
version: "0.8.0"
},
{
version: "0.6.12"
}
]
}
