I’m trying to load a variable from the .env file inside my generate-keypair.ts file. I’m using dotenv to load the environment variables and esrun to run the TypeScript file. Both my .env file and TypeScript file are in the same directory.

But it keeps giving me this error:

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

Did you mean to import "../dotenv/config.js"?

}

Node.js v20.12.1

Here’s my generate-keypair.ts file:

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

console.log(process.env.SECRET_KEY);

const keypair = getKeypairFromEnvironment('SECRET_KEY');

console.log(`✅ Finished! We've loaded our secret key securely, using an env file!`);

When I comment the import "dotenv/config" the code runs without error but gives undefined for the process.env.SECRET_KEY variable.

How can I read the exact value of the SECRET_KEY variable from the .env file instead of undefined?
