Lesson 4: compiler problem

[pharrell04]

I am @4:15:20 of the course, I tried compiling along with him but it fails. I have reviewed my code to make sure it matches with his and it continues to say "Error: not found contracts/@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol". I would add the code to show a certain section but it doesn't specify where my mistake is. May anyone tell me what I should do from here to continue the course. Should I follow the rest of this course along without coding?

Please provide your smart contract.

//GOALS FOR CONTRACT:
//get funds from users
//withdraw funds
//set a minimum funding value in USD

//SPDX-License-Identifier: MIT
pragma solidity ^0.8.8;

import "./@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";

contract FundMe {

uint256 public minimumUSD = 50;

function fund() public payable {
    //smart contracts can hold funds just like wallets 
    require(msg.sender >= 1e18, "Didnt Send Enough"); //funds are in wei so you need it to the 18th power
}

function getPrice() public view returns(uint256) {
AggregatorV3Interface priceFeed = AggregatorV3Interface(0x8A753747A1Fa494EC906cE90E9f37563A8AF630e);
(,int price,,,) = priceFeed.latestRoundData();
return uint256(price * 1e10);
}

function getVersion() public view returns (uint256) {
AggregatorV3Interface priceFeed = AggregatorV3Interface(0x8A753747A1Fa494EC906cE90E9f37563A8AF630e);
return priceFeed.version();
}

If you need me to provide my contract in another way/form just let me know (I am new to all of this). Thank you btw

Here is your problem

import "./@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";

Channge this line to

import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";

Hi there @pharrell04 !

If you already imported the contracts as @adityabhattad2021 pointed out
import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";

Make sure you did not forget to download the contracts from the chainlink repo first :)
yarn add --dev "@chainlink/contracts"

[pharrell04]

Thank you, may you explain how to download the contracts from the repo ? sorry for the confusion

[mattaereal]

It's the command I added above, yarn add downloads / installs a package, and this package contains chainlink's contracts:
yarn add --dev "@chainlink/contracts"

So this will automatically download all their contracts, and store them inside node_modules/chainlink/contracts folder.
