Error: Unable to load vendor autoloader in bootstrap.php

Encountering a PHP error because the bootstrap file cannot locate the vendor autoloader. Below is an alternative code snippet:

<?php
define('LIB_DIR', __DIR__ . '/lib/');

if (!file_exists(LIB_DIR . 'loader.php')) {
    exit('Loader file is missing');
}

require LIB_DIR . 'loader.php';
?>

Reviewing the file paths more carefully may help. Sometimes the computed path in code does not match the actual server directory, especially if different execution environments are involved. I experienced a similar issue when my project directory structure was slightly off from what my code expected, resulting in unexpected file include problems. The solution involved manually verifying each directory constant and ensuring that all composer files were properly installed with the necessary autoload configurations. Consolidating these checks often reveals subtle mistakes that cause the autoloader not to load as intended.

Hey everyone, I ran into a somewhat similar situation not too long ago and it really made me pause for a minute. It seems that sometimes it’s not just about the code snippet but also about how your environment expects things to be set up. I wonder if maybe someone has seen any weird behavior when the base path or directory structure isn’t exactly what the autoloader expects. Have you ever had an issue where a slight difference in the server setup or even a small misconfiguration in your composer files ended up throwing off the autoloader?

For me, double-checking the defined paths and ensuring that my vendor directory got created properly after running composer install was key. It would be interesting to hear if anyone has taken alternative troubleshooting approaches in cases like this. Cheers to figuring it out together!
