TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider') - already tried all suggestions in this discussion and it still doesn't work

[RichardKoh1]

I tried to change the version of ethers, deleted node_modules and reinstalled everything and I still get the same issue. Not sure where to go from here.

Node.js v18.14.2

Here's my code:
package.json

{
  "dependencies": {
    "ethers": "^5.6.2",
    "fs-extra": "^11.1.0",
    "solc": "0.8.8"
  },
  "scripts": {
    "compile": "yarn solcjs --bin --abi --include-path node_modules/ --base-path . -o . SimpleStorage.sol"
  }
}

deploy.js

const ethers = require("ethers");
const fs = require("fs-extra");
async function main() {
  // http://127.0.0.1:7545

  const provider = new ethers.prodivers.JsonRpcProvider(
    "http://127.0.0.1:7545"
  );
  const wallet = new ethers.Wallet(
    "0xb88d03505701db297c497a32663797652b5d951c781b3c2262fb8d0308931dad",
    provider
  );
  const abi = fs.readFileSync("./SimpleStorage_sol_SimepleStorage.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(); //Stop here! Wait for contract to deploy
  console.log(contract);
}

Any help would be appreciated, thanks!

@RichardKoh1 Make sure in your scripts Process should be process with lower case p.

@VictorBassey-web install ethers version 5. npm install --save-dev ethers@^5
