someone to help me in a lesson related to "FORK" lesson 7-11 around the timeline of 51:28

[Dorane-Star]

i was deploying three contracts on foundry, these are as follows:

first:

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.19;

import {Test} from "forge-std/Test.sol";
import {FundMe} from "../src/FundMe.sol";

contract FundMeTest is Test {
    FundMe fundMe;

    function setUp() external {
        fundMe = new FundMe();
    }

    function testMinimumDollarIsFive() public view {
        assertEq(fundMe.MINIMUM_USD(), 5e18);
    }

    function testOwnerIsMsgSender() public view {
        assertEq(fundMe.i_owner(), address(this));
    }

    function testPriceFeedVersionIsAccurate() public view {
        uint256 version = fundMe.getVersion();
        assertEq(version, 4);
    }
}

second one:

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.18;

import {Script} from "forge-std/Script.sol";

contract HelperConfig is Script {
    NetworkConfig public activeNetworkConfig;

    struct NetworkConfig {
        address priceFeed;
    }

    constructor() {
        if (block.chainid == 11155111) {} else {
            activeNetworkConfig = getSepoliaEthConfig();
        }
    }

    function getSepoliaEthConfig() public pure returns (NetworkConfig memory) {
        NetworkConfig memory sepoliaconfig = NetworkConfig({
            priceFeed: 0x8A753747A1Fa494EC906cE90E9f37563A8AF630e
        });
        return sepoliaconfig;
    }

    function getAnvilEthConfig() public pure {}
}

thrid one:

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.18;

import {Script} from "forge-std/Script.sol";
import {FundMe} from "../src/FundMe.sol";
import {HelperConfig} from "./HelperConfig.s.sol";

contract DeployFundMe is Script {
    function run() external returns (FundMe) {
        HelperConfig helperConfig = new HelperConfig;
        address ethUsdPriceFeed = helperConfig.activeNetworkConfig;

        vm.startBroadcast();
        FundMe fundMe = new FundMe(ethUsdPriceFeed);
        vm.endBroadcast();
        return fundMe;
    }
}

The command is used to compile was : "forge test --fork-url $SEPOLIA_RPC_URL "

The error ecountered is :

error: a value is required for '--fork-url <URL>' but none was supplied

so what is the problem? i can see P Collins is getting succesfull compilation within the same context!

Hello @Dorane-Star, Please ensure that you run source .env before running forge test --fork-url $SEPOLIA_RPC_URL and also ensure that you check your .env to be sure that you have spelt SEPOLIA_RPC_URL correctly.

[Dorane-Star]

thanks @EngrPips , but how do i find the source. env plz?

[EngrPips]

Do you have a .env file in your working directory?

[Dorane-Star]

let me show a screenshot of my platform plz

[Dorane-Star]

that is a screenshot of my platformm

[EngrPips]

You must have missed the part where Patrick created a .env file and added the required information to it, Please re-watch the lesson from the beginning.

[Dorane-Star]

ok thanks......i remember him adding such file but i deleted as some point.......but many thanks

You are welcome, Friend. You actually need it now.
