<No solution works!> TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

[lqpchen]

Hey guys, I bumped into this issue when following this video at 7:07:00, and I tried all solutions from similar post but none worked so far.

I got this error message when running node deploy.js
I'm using win11 and have set the Ganache server to be vEthernet(WSL) and made sure the ethers version is 5.7.2

My code for this file is as follows:

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

async function main() {
  // compile separately
  // http://127.0.0.1:7545
  // console.log(ethers.provider.JsonRpcProvider); // this produce the same error
  const provider = new ethers.provider.JsonRpcProvider(
    "http://172.22.48.1:7545" // after setting vEthernet (WSL) in Ganache Win11
  );
  console.log("here");
  const wallet = new ethers.Wallet(
    "cabfa4caf52f1cb467a3898e748d1b06852efeca71fa41a048a25caf4a5bc813", // private key copied from Ganache
    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, please wait...");
  const contract = await contractFactory.deploy();
  console.log(contract);
}

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

My package.json is as follows:

{
  "dependencies": {
    "ethers": "5.7.2",
    "fs-extra": "^11.1.0",
    "ganache": "^7.7.4",
    "solc": "0.8.7-fixed"
  },
  "scripts": {
    "compile": "yarn solcjs --bin --abi --include-path node_modules/ --bath-path . -o . SimpleStorage.sol"
  }
}

Any suggestions would be much appreciated. Thanks!

@lqpchen It is ethers.providers not provider

[lqpchen]

Oh thanks for the quick reply! I even didn't notice the difference when I compared my code and the github one line by line..

[fraolme]

could be different package versions but ethers.providers.JsonRpcProvider didn't work for me. What worked was ethers.JsonRpcProvider

@firaa-ol Yes, now in the latest version this is the pattern.
