You attempted to import the Node standard library module "path" from "env.js"

Summary:

when trying to run the project i have this error:

You attempted to import the Node standard library module "path" from "env.js".

this is my env.js file:

/*
 * Env file to load and validate env variables
 * Be cautious; this file should not be imported into your source folder.
 * We split the env variables into two parts:
 * 1. Client variables: These variables are used in the client-side code (src folder).
 * 2. Build-time variables: These variables are used in the build process (app.config.ts file).
 * Import this file into the `app.config.ts` file to use environment variables during the build process. The client variables can then be passed to the client-side using the extra field in the `app.config.ts` file.
 * To access the client environment variables in your `src` folder, you can import them from `@env`. For example: `import Env from '@env'`.
 */
/**
 * 1st part: Import packages and Load your env variables
 * we use dotenv to load the correct variables from the .env file based on the APP_ENV variable (default is development)
 * APP_ENV is passed as an inline variable while executing the command, for example: APP_ENV=staging pnpm build:android
 */
const z = require('zod');

const packageJSON = require('./package.json');
const path = require('path');
const APP_ENV = process.env.APP_ENV ?? 'development';
const envPath = path.resolve(__dirname, `.env.${APP_ENV}`);

require('dotenv').config({
  path: envPath,
});

/**
 * 2nd part: Define some static variables for the app
 * Such as: bundle id, package name, app name.
 *
 * You can add them to the .env file but we think it's better to keep them here as as we use prefix to generate this values based on the APP_ENV
 * for example: if the APP_ENV is staging, the bundle id will be com.nordiccar.mypartslocator.staging
 */

// TODO: Replace these values with your own

 * we use zod to define our env variables schema

 * we split the env variables into two parts:
 *    1. client: These variables are used in the client-side code (`src` folder).
 *    2. buildTime: These variables are used in the build process (app.config.ts file). You can think of them as server-side variables.
 *
 * Main rules:
 *    1. If you need your variable on the client-side, you should add it to the client schema; otherwise, you should add it to the buildTime schema.
 *    2. Whenever you want to add a new variable, you should add it to the correct schema based on the previous rule, then you should add it to the corresponding object (_clientEnv or _buildTimeEnv).
 *
 * Note: `z.string()` means that the variable exists and can be an empty string, but not `undefined`.
 * If you want to make the variable required, you should use `z.string().min(1)` instead.
 * Read more about zod here: https://zod.dev/?id=strings

@iamhaaamed - what does your babel config look like?

This is my babel.config file:
