第66行上的cpanel vendor / composer / autoload_real.php上的Laravel错误

Question

Warning: require(/home/user/public_html/webfolder/vendor/composer/../../app/http/helpers.php): failed to open stream: No such file or directory in /home/user/public_html/webfolder/vendor/composer/autoload_real.php on line 66

I have created a custom helpers.php

My composer.json

"autoload": {
        "files": [
        "app/http/helpers.php"
        ],  
        "classmap": [
            "database/seeds",
            "database/factories"
        ],
        "psr-4": {
            "App\\": "app/"
        }
    },

My account on cpanel dont have SSH access, so I cannot run composer dump-autoload or any composer commands. Please help, thanks in advance!!!
