README.md

I followed the instructions by commenting the lines

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

and replacing them with

import { ethers } from "ethers"
import * as fs from "fs-extra"
import "dotenv/config" 

now, in deploy.ts file

async function main() {
const provider = new ethers.providers.JsonRpcProvider(process.env.RPC_URL)
    const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider)
    ...
}

and in encryptKey.ts file

async function main() {
    const wallet = new ethers.Wallet(process.env.PRIVATE_KEY)
    const encryptedJsonKey = await wallet.encrypt(
        process.env.PRIVATE_KEY_PASSWORD,
        process.env.PRIVATE_KEY
    )

<process.env.PRIVATE_KEY> in both files is giving the error

var process: NodeJS.Process
Argument of type 'string | undefined' is not assignable to parameter of type 'BytesLike | ExternallyOwnedAccount | SigningKey'.
  Type 'undefined' is not assignable to type 'BytesLike | ExternallyOwnedAccount | SigningKey'.ts(2345)

I tried uncommenting const ethers = require("ethers"), replacing import { ethers } from "ethers" and the error is gone but when run,

(node:10196) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
import * as fs from "fs-extra"
^^^^^^

please help!

For Es6 import you need to import the fs module like this: import fs from "fs-extra";
