Install CodeIgniter 4 on Shared Hosting

Thanks for your answer, this error is shown:

Warning: require(../vendor/codeigniter4/framework/system/bootstrap.php): failed to open stream: No such file or directory in /home/mhd-01/www.-----------.com/htdocs/test/index.php on line 36

Fatal error: require(): Failed opening required '../vendor/codeigniter4/framework/system/bootstrap.php' (include_path='.:/usr/share/php') in /home/mhd-01/www.------.com/htdocs/test/index.php on line 36

Also, leaving the .htaccess file releases a 505 error
