Error when importing secret key from .env

Question

I am working through https://www.soldev.app/course/intro-to-cryptography

and at the point where I am attempting to import the secret key from a .env

I am getting an error:

My keypair is set using:

import { Keypair } from "@solana/web3.js";

const keypair = Keypair.generate();

console.log(The public key is: , keypair.publicKey.toBase58()); console.log(The secret key is: , keypair.secretKey); console.log(✅ Finished!);

not sure how to resolve it as I am already using a base58.. Any help would be appreciated

Answer 1

Looks like it is expecting you to have a keypair in your .env file.

You can just create that file next to your ts files and add the key

SECRET_KEY=[yourkeypair]

You can generate a new one like so:

solana-keygen grind --starts-with dev:1

and then copy the contents into your .env file

Then you can also get the address

solana address keypair.json 

and then airdrop some sol to it for example:

solana airdrop -k keypair.json

I did the exact same as the steps but end up getting this error:

node:internal/process/esm_loader:34
      internalBinding('errors').triggerUncaughtException(
                                ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find module 'F:\web3-solana\generate-keypair\node_modules\.bin\node_modules\dotenv\config.js' imported from F:\web3-solana\generate-keypair\node_modules\.bin\esrun-1723786154129.tmp.mjs
Did you mean to import "../dotenv/config.js"?

@GoodBurger Any idea how to resolve this, i have spent almost two-three hours but can't get rid of this issue. It only comes when i want to load the variable from .env file. Rest of the code is working fine as excepted.
