Problem with deployment.

[dannyakorede12]

Hello, I'm in lesson 4 and on the ethers chapter.
I just tried to deploy my code after adding the ethers and fs-extra.
having added all the const i am hit with the particular error below when trying to deploy.

/ether-simple-storage# node deploy.js
TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')
at main (/root/ether-simple-storage/deploy.js:6:40)
at Object. (/root/ether-simple-storage/deploy.js:22:1)

I am a bit confused as i checked the code itself and i am not sure of where the problem is coming from.

here is the code i used in my VS code

`const ethers = require("ethers");
const fs = require("fs-extra");
// http://127.0.0.1:7545

async function main() {
constprovider = new ethers.providers.JsonRpcProvider("http://127.0.0.1:7545");
const wallet = new ethers.wallet(
0xf7ee25516153f537c57cd6c414514df887e8b89e4f8c1960d102446bc80bb8a9,
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);
});`

i installed ethers with npm instead of yarn and it worked

[dannyakorede12]

i just tried that but, it's the same

[dannyakorede12]

thank you for your response though

[lordshady1000]

npm install ethers@^5.7.2

[dannyakorede12]

still getting the same error.

but i have attached the code below

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

// http://127.0.0.1:7545

async function main() {
const provider = new ethers.provider.JsonRpcProvider("http://127.0.0.1:7545");
const wallet = new ethers.Wallet(
0xd7b1ca7596a6e31d328a7e4655ba9a1030014922aa6a71838b2a8cc152c7f3f0,
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();
const transactionReceipt = await contract.deploymentTransaction.wait(1);
console.log("here is the deployment transaction: ");
console.log(contract.deployTransaction);
console.log("here is the deployment receipt: ");
console.log(transactionReceipt);
}

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

have your same issue.

this is the code which looks ok to me:
'''javascript
//Solidity is synchronous
//Javascript can be asynchronous
const ethers = require("ethers"); //mi permette di comunicare con una blockchain (in questo caso Ganache)
const fs = require("fs-extra");

async function main() {
// console.log stampa a schermo il contenuto tra parentesi
//http://0.0.0.0:8545
const provider = new ethers.providers.JsonRpcProvider(
"http://127.0.0.1:7545"
);
const wallet = new ethers.Wallet(
"0xd71e341a59df09a0c7ba179d42750070f2131018fbd3c90f9a5007e651c9f7d4",
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...");
7545;
const contract = await contractFactory.deploy();
//console.log(contract);
}

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

I run command: node deploy.js from terminal and get the following error:
TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')
at main (/home/user/hh-fcc/ether-simple-storage/deploy.js:9:41)

Looks like it cannot connect to the ganache blockchain or something similar

Hey guys, I think they change the syntax a little. You just need to change the declaration of provider to the following

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