Error: No Contract deployed with name FundMe

[amirxoder]

This error is driving me crazy
I check every thing several time, what the hell is going here??

I should also add that I code in the Windows environment NOT WSL

yarn hardhat test

and then i face to this f***ing Error:

Error: No Contract deployed with name FundMe

fundme unit test:

const { assert } = require("chai");
const { deployments, ethers, getNamedAccounts } = require("hardhat");

describe("FundMe", () => {
  let fundMe;
  let mockV3Aggregator;
  let deployer;
  const sendValue = ethers.utils.parseEther("1");
  beforeEach(async () => {
    // const accounts = await ethers.getSigners();
    // deployer = accounts[0];
    deployer = (await getNamedAccounts()).deployer;
    await deployments.fixture(["all"]);
    fundMe = await ethers.getContract("FundMe", deployer);
    mockV3Aggregator = await ethers.getContract("MockV3Aggregator", deployer);
  });

  describe("construcotor", () => {
    it("sets ths aggregator addresses correctly", async () => {
      const response = await fundMe.priceFeed();
      assert.equal(response, mockV3Aggregator.address);
    });
  });
});

this one is 00-deploy-mocks.js

const { network } = require("hardhat");

  developmentChain,
  DECIMAL,
  INITIAL_ASNWER,

module.exports.default = async ({ getNamedAccounts, deployments }) => {

@amirxoder you need to parse args in your 01-deploy-fund-me.js file so you need to change this
before

  const fundMe = await deploy("FundMe", {
    from: deployer,
    args,
    log: true,
    waitConfirmations: network.config.blockConfirmation || 1,
  });

after

  const fundMe = await deploy("FundMe", {
    from: deployer,
    args:args,
    log: true,
    waitConfirmations: network.config.blockConfirmation || 1,
  });

then try to run

[amirxoder]

I made the changes but I still get the same damn error bro
according to the ES6 standard, there is no need to repeat when our key and value are equal

[amirxoder]

I think module.exports.tags not working in windows os :))

[HarshDev56]

@amirxoder in your 01-deploy-fund-me.js file change this line

  const ethUsdAggregator = await get("MockV3Aggregator");

to this

  const ethUsdAggregator = await deployments.get("MockV3Aggregator");

[amirxoder]

Done... but still the same error

const { network, run } = require("hardhat");
const { networkConfig, developmentChain } = require("../helper-hardhat-config");
const { verify } = require("../utils/verify");

module.exports.default = async ({ getNamedAccounts, deployments }) => {
  const { deploy, log, get } = deployments;
  const { deployer } = await getNamedAccounts();

  const chainId = network.config.chainId;
  let ethUsdPriceFeedAddress;

  if (developmentChain.includes(network.name)) {
    const ethUsdAggregator = await deployments.get("MockV3Aggregator");
    ethUsdPriceFeedAddress = ethUsdAggregator.address;
  } else {
    ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeedAddress"];
  }

  const args = [ethUsdPriceFeedAddress];

  const fundMe = await deploy("FundMe", {
    from: deployer,
    args: args,
    log: true,
    waitConfirmations: network.config.blockConfirmation || 1,
  });
  if (
    !developmentChain.includes(network.name) &&
    process.env.ETHERSCAN_API_KEY
  ) {
    await verify(fundMe.address, args);
  }
  log("---------------------------------------------");
};

module.exports.tags = ["all", "fundme"];

ok give me the link of the repo i will check

[amirxoder]

here u are

@amirxoder Remove default from these exports otherwise script will not be able to detect tags export module.exports.default

[amirxoder]

yeapp ,its worked!
thanks man

[Amity808]

01-deploy-fund-me.js for reference in this file. Thanks, it works for me.

[HarshDev56]

@amirxoder Remove default from these exports otherwise script will not be able to detect tags export module.exports.default then also add getPriceFeed in your FundMe.sol file otherwise you will get one more error .

[amirxoder]

Thanks Bro
