带有环境变量的警告。 无法连接到数据库

Question

I just finished making an .env file for my wordpress project and when I finished typing in all the values the backend of my wordpress won't work. It says it can't connect to the database. this is the error:

Warning: mysqli_real_connect(): (HY000/1045): Access denied for user ''@'localhost' (using password: NO) in /home/vagrant/Code/creativeforces/wp-includes/wp-db.php on line 1489

Here is my wp-config.php:

define('DB_NAME', getenv('DB_NAME'));

// /** MySQL database username */
define('DB_USER', getenv('DB_USER'));

// /** MySQL database password */
define('DB_PASSWORD', getenv('DB_PASSWORD'));

// /** MySQL hostname */
define('DB_HOST', getenv('DB_HOST'));

// /** Database Charset to use in creating database tables. */
define('DB_CHARSET', getenv('DB_CHARSET'));

// /** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', getenv('DB_COLLIATE'));

define('AUTH_KEY', getenv('AUTH_KEY'));
define('SECURE_AUTH_KEY', getenv('SECURE_AUTH_KEY'));
define('LOGGED_IN_KEY', getenv('LOGGED_IN_KEY'));
define('NONCE_KEY',    getenv('NONCE_KEY'));
define('AUTH_SALT',  getenv('AUTH_SALT'));
define('SECURE_AUTH_SALT', getenv('SECURE_AUTH_SALT'));
define('LOGGED_IN_SALT',   getenv('LOGGED_IN_SALT'));
define('NONCE_SALT',    getenv('NONCE_SALT'));

I'm not sure why it's not connecting to my env file. Here is an image of my file structure:

also this is what my .env file looks like but these are not the values I have. These are just examples.

DB_NAME=cupcakelife
DB_HOST=44.33.22
DB_DATABASE=cupcake
DB_USER=cupcake
DB_PASSWORD=bakinglife
DB_CHARSET=dewqdwe
DB_COLLIATE='dewqdfwrfvgerwfgrewfvwerferw'

any help would be appreciated!

Ok, so getenv() gets the value of environment variables. AFAIK, Vagrant's vars from .env aren't populated to that scope unless you specifically tell it to. Check this out: https://github.com/vlucas/phpdotenv it should do the trick for you.
