Why Fatal error: Uncaught Error: Class 'Illuminate\Foundation\Application' not found

Question

I have a Laravel/Homestead project that is finally working locally. Now I'm trying to port it over to HostGator and can't get it running due to titled error. I've tried all the suggested solutions to no avail. Including:

composer require laravel/laravel
composer dump-autoload
composer install --no-scripts
composer update
composer update --no-scripts

Nothing works. Same error. If this is a clue, I also tried

php artisan clear-compiled

and get response of

Could not open input file: artisan

I'm about ready to give up on Laravel/Homestead. I've spent countless hours on this framework with nothing but problems to show for it. Would not recommend it to anybody.

You can see the error yourself here: http://www.tekknow.net/MedAverter/medaverter/

Any suggestions before I throw in the towel?

Answer 1

For the artisan file, the artisan file is not required through includes, you have it in your root project, which is created when you create your Laravel project. Here is the file .

So you need to have that file in your project.

For the missing class, you try to require laravel/laravel but that is not the correct dependency. Again that github repo is a shell for a project, to have Laravel features you need to base of laravel/laravel and include laravel/framework .

Hope this clears up some confusing and can get you on the right track. Secondly you shouldn't port it over, but simply cloning your project and running composer install should be sufficient.

Answer 2

The problem turned out to be two issues. 1. The wrong version of PHP was running. If I ssh'ed into the hostgator server and did

php -v

It showed PHP 5.6.30 even though I had selected Php 7.1 in the cPanel PHP Selector. If I did

tekknow.net/phpinfo.php

it would say I was using 7.1. Called up HostGator tech support and they were able to change it to PHP 7.3.13.

Now if I do:

php artisan clear cache

I no longer get the error about

Parse error: syntax error, unexpected '?' in /home1/sl1k7f3j/public_html/medaverter/bootstrap/app.php on line 15

which was an error caused by a version of php that doesn't support the ?? operator.

2. The second problem was a lack of memory issue. If I did

   composer update It would start to work but would fail in about 30 seconds with

Fatal error: Out of memory (allocated 709623808) (tried to allocate 34187559 bytes) in phar:///opt/cpanel/composer/bin/composer/src/Composer/Json/JsonFile.php on line 270

The HostGator tech rep could not figure out why that was happening but I got around that issue by manually uploading my local vendor folder to the host server.

Now when I go to http://tekknow.net/medaverter/ it works!
