I am upgrading a Drupal 8 site to Drupal 9. I removed the core, vendor, modules, and contrib directories; I ran composer install. All went well, but when I refreshed the page, I saw the following error.
Warning: require(/app/docroot/../vendor/autoload.php): failed to open stream: No such file or directory in /app/docroot/autoload.php on line 16 Fatal error: require(): Failed opening required '/app/docroot/../vendor/autoload.php' (include_path='.:/usr/local/lib/php') in /app/docroot/autoload.php on line 16
The content of the composer.json file is the following one.

How can I fix this autoload issue?
