An error in importing

this is my contract:

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.19;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract LION is ERC20

And this error is related to my import:

Source "@openzeppelin/contracts/token/ERC20/ERC20.sol" not found: File import callback not supported

what is solution?
(I have installed openzeppelin contracts using the following code:

npm install @openzeppelin/contracts
