    let wallet = new ethers.wallet(process.env.PIVATE_KEY, provider)
    const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf-8")
    const binary = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.bin", "utf8")
    const contractFactory = new ethers.ContractFactory(abi, binary,wallet)

@malommey Which ethers version are you using?

[malommey]

5.7.2

[alymurtazamemon]

@malommey then you should not use ethers.JsonRPCProvider instead use ethers.providers.JsonRpcProvider

[malommey]

it didnt go away..

[alymurtazamemon]

@malommey ? Please leave your repository link.

In case you do not know how to upload code to GitHub and check this out #2637

[vishwa7dcap786]

after changing to ethers.providerJsonRpcProvider
what error you got

[malommey]

TypeError: ethers.JsonRPCProvider is not a constructor

[hiteshgupta2507]

Can you copy and paste your whole code? Also what version of solidity are you using?

[malommey]

i did

[hiteshgupta2507]

can you try running your code after upgrading to this ether version?

yarn upgrade ethers@^5.7.2

[malommey]

i have tried version 5.7.2 and 6.3.0

[vishwa7dcap786]

better you should upgrade to etherjs 6.3.0

[malommey]

i have

[MattBCarr]

change ethers.JsonRPCProvider to ethers.JsonRpcProvider

[malommey]

i did that

[malommey]

nothing work

[rainbowginger]

Could you solve it?

[HarshDev56]

@malommey you need to change in this line you need to change s to S in simpleStorage.sol
before
const abi = fs.readFileSync("./simpleStorage.sol_SimpleStorage.abi", "utf8");
After
const abi = fs.readFileSync("./SimpleStorage.sol_SimpleStorage.abi", "utf8");

[malommey]

still stuck. trying to push my code

Hi @malommey

1. you should spill PRIVATE_KEY correctly.
2. you have declared provider and passed it as an argument to JsonRpcProvider
3. I don't see you invoked the function main() at the end
4. also check your .env file and see if you have any misspellings or incorrect values.

const ethers = require("ethers")
const fs = require("fs-extra")
const solc = require("solc")
require("dotenv").config()

   async function main(){
    let provider =new ethers.JsonRpcProvider(process.env.RPC_URL, provider) // delete the passed argument **provider** 
    let wallet = new ethers.wallet(process.env.PIVATE_KEY, provider) // spill PRIVATE_KEY correctly
    const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf-8")
    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()

   }  
// invoke the function main() here

i have made the changes, the error is coming from the wallet
“””
let wallet = new ethers.wallet(process.env.PRIVATE_KEY, provider)/// when i removed the provider
“””
error type
“””
cannot read properties of wallet
“””

thanks

[hiteshgupta2507]

It's Wallet (with 'W" uppercase)

let wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider);
