Be sure that you are using Dotenv after loading from vendor/autoload.php.

For example, I was using OpenCart, in which contained a file startup.php with:

// Autoloader
if (file_exists(DIR_VENDOR . 'autoload.php')) {
    require_once(DIR_VENDOR . 'autoload.php');
}

And I had defined DIR_VENDOR in config.php as:

define('DIR_VENDOR', __DIR__.'/vendor/');

So finally, in index.php, I would have:

// Startup
require_once(DIR_SYSTEM . 'startup.php');

// dotenv
$dotenv = new Dotenv\Dotenv(__DIR__);
$dotenv->load();

So startup.php loads vendor/autoload.php, which loads vlucas/phpdotenv, after which we can then find Dotenv\Dotenv.

with "vlucas/phpdotenv": "^5.4" it now works like this:

<?php
require 'vendor/autoload.php';

use Dotenv\Dotenv;

$dotenv = Dotenv::createImmutable(__DIR__);
$dotenv->load();

or

<?php
require 'vendor/autoload.php';

$dotenv = Dotenv\Dotenv::createImmutable(__DIR__); //Notice the Namespace and Class
$dotenv->load();

check if you have "vlucas/phpdotenv" : "~2.2" in "require" tag in composer file. if you don't then add that plugin and open your terminal and run "composer dump-autoload" then run "composer update". and just to be safe run "composer dump-autoload" once again to refresh all the file paths.

and, if you do have phpdotenv plugin then add that plugin in "require" then just run the dump-autoload command.

For me worked this code:

use Dotenv\Dotenv;

require __DIR__ . '/../vendor/autoload.php';

$dotenv = new Dotenv(__DIR__ . "/..");
$dotenv->load();

Instead of this:

require __DIR__ . '/../vendor/autoload.php';

$dotenv = new Dotenv/Dotenv(__DIR__);
$dotenv->load();

I'm using the PhpStorm IDE and I installed dotenv on the server via SSH. Subsequently I didn't have the new vendor files in the local directory which caused this error. I simply downloaded the up-to-date vendor folder from the server (overwriting the local one) and the error went away.

What helped me:

Delete vendor folder fully;
Delete vlucas/phpdotenv library from a composer.json;
Delete composer.lock itself;
Run composer install to initiate again vendor folder and composer.lock file;
Run composer require vlucas/phpdotenv again to download the library.

It may still say Undefined type 'Dotenv\Dotenv'.intelephense(1009) on your code editor but on your localhost your project should load without an error. Hope it helps!

Make sure your path to autoload.php is correct '../vendor/autoload.php';
