Lesson 5 i keep getting TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

[Emmanuel-Sokoyebom]

Here's my code:

const { ContractFactory } = require("ethers");
const ethers = require("ethers");
const fs = require("fs-extra");

async function main() {
  // http://127.0.0.1:7545
  const provider = new ethers.provider.JsonRpcProvider("HTTP://127.0.0.1:754");
  const wallet = new ethers.wallet(
    "0x600dbe54589f60a7aa2e1c6db2c8aecfc644240baaf0c62615577b3c2c025f7f",
    provider
  );
  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf8"
  );
  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying, Pleae wait..");
  const constract = ContractFactory.deploy();
  console.log(contract);
}
main()
  .then(() => Process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

heres the error that keep popping :

If you're ethers version is above 6, you need to change your code to this:

let provider = new ethers.JsonRpcProvider("http://172.31.96.1:7545");
let wallet = new ethers.Wallet(
    "<private key>",
    provider
);

and you're using the Ubuntu system (WSL), you need to change your RPC_URL as well

thank you.

i tried it, but its still giving me the same error

[dauntless001]

first of all copy the right rpc_url ( You seem to be missing the last 5 ) then downgrade ethersjs to v5.7.2

`npm install [email protected]

[Emmanuel-Sokoyebom]

the rpc_url on my ganashe is the same, no extra 5
are u saying i should just add 5 to the ending of my rpc_url

i tried all that and it's bing up this error:

TypeError: ethers.JsonRpcProvider is not a constructor
