const { ethers, JsonRpcProvider } = require("ethers")
// and
const provider = new JsonRpcProvider("http://0.0.0.0:7545")

[42maojin]

check ethers version, is the key,reason is version update

[roostiqcopilot]

const { ethers, JsonRpcProvider } = require("ethers") // and const provider = new JsonRpcProvider("http://0.0.0.0:7545")

Hey guys, I'll copy-paste an answer I gave, I was stuck on the same problem.

const { ethers } = require("ethers");
const fs = require("fs");

async function main() {
const provider = new ethers.providers.JsonRpcProvider(
"http://127.0.0.1:7545/"
);
const wallet = new ethers.Wallet(
"0xb357c12e59c02b0b6bde61434adda8ab38a29f2db7bb109ec360955b55404677",
provider
);
const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
const bin = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.bin", "utf8");
const contractFactory = new ethers.ContractFactory(abi, bin, wallet);
console.log("Deploying, please wait...");
const contract = await contractFactory.deploy(); // Stop here and wait for the contract to deploy
const deploymentReceipt = await contract.deployTransaction.wait(1);
console.log(deploymentReceipt);
}

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

I unistalled the node_modules and reinstalled it. Also I'm using Ethers 5.6.2 and modify a little bit of the code listening to some this and input from ChatGPT. Good luck bro!

what i got to know in the later versions the file structure was more well defined so as to put the jsonRpcProvider in the providers , but in the earlier section the JsonRpcProvider was in the ethers itself

you can try this instead

const provider = new ethers.JsonRpcProvider(
"http://127.0.0.1:7545/"
);
