MODULE NOT FOUND

Question

import * as dotenv from 'dotenv';
dotenv.config();

import { getKeypairFromEnvironment } from '@solana-developers/helpers';


const keypair = getKeypairFromEnvironment("SECRET_KEY");
console.log("Public Key:", keypair.publicKey.toString());
console.log("Private Key:", keypair.secretKey);

Output Generated is Public Key: HprpzYy7V6fJx2RCxsUUb9TtsFn8cY5mo2ZyoF2aowVi Private Key: Uint8Array(64) [ 79, 188, 209, 86, 157, 233, 52, 172, 3, 196, 91, 151, 109, 136, 74, 225, 198, 59, 224, 15, 173, 34, 85, 233, 75, 44, 212, 164, 111, 85, 175, 238, 249, 253, 161, 1, 119, 173, 57, 39, 187, 150, 243, 216, 59, 52, 191, 4, 68, 53, 177, 12, 253, 170, 172, 69, 68, 195, 85, 207, 241, 168, 202, 121 ]

But when i run another program that also needs keypair

import * as dotenv from 'dotenv';
dotenv.config();
import {
  getExplorerLink, getKeypairFromEnvironment,
} from "@solana-developers/helpers";

import { mintTo } from "@solana/spl-token";


import { Connection, PublicKey, clusterApiUrl } from "@solana/web3.js";
const connection = new Connection(clusterApiUrl("devnet"));

// Our token has two decimal places
const MINOR_UNITS_PER_MAJOR_UNITS = Math.pow(10, 2);

const user = await getKeypairFromEnvironment("SECRET_KEY");


// Subtitute in your token mint account from create-token-mint.ts
const tokenMintAccount = new PublicKey(
  "YOUR_TOKEN_MINT_ACCOUNT"
);

// Substitute in your own, or a friend's token account address, based on the previous step.
const recipientAssociatedTokenAccount = new PublicKey(
  "RECIPIENT_TOKEN_ACCOUNT"
);

const transactionSignature = await mintTo(
  connection,
  user,
  tokenMintAccount,
  recipientAssociatedTokenAccount,
  user,
  10 * MINOR_UNITS_PER_MAJOR_UNITS
);

const link = getExplorerLink("transaction", transactionSignature, "devnet");

console.log(`✅ Success! Mint Token Transaction: ${link}`);

I always get this error:

Answer 1

To resolve the error you're encountering, ensure you are in the project root directory and run the following command to install the required package: :

npm i @solana-developers/helpers

This should help you resolve the ERR_MODULE_NOT_FOUND error and ensure that your script runs correctly.
