My deploy.js

const ethers = require("ethers");
const fs = require("fs-extra");

async function main() {
    //compile them in our code
    //compile them seperately
    //http://127.0.0.1:7545
    const provider = new ethers.providers.JsonRpcProvider("http://127.0.0.1:7545");
    const wallet = new ethers.Wallet("0xc4e6ed033bec6c6f706ec870a866ed9e77a4012a468e39bf2f94efb9a092959c",provider);
    const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi","utf8");
    const binary = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.bin","utf8");
    const contractFactory = ethers.ContractFactory(abi,binary,wallet);
    console.log("Deploying, please wait...");
    const contract = await contractFactory.deploy(); //stop here wait for the contract to deploy
    console.log(contract);
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

What worked for me was using ethers 6.6.2 only but removing ".providers" from the syntax.

 let provider = new ethers.JsonRpcProvider("http://127.0.0.1:8545");
