Fatal error: Class 'Illuminate\Foundation\Application' not found in /path/to/project/bootstrap/app.php on line 14

That shouldn't impact your development environment, because with APP_DEBUG=true, you're not using the compiled file anyway. Have you tried running composer dumpauto?

@bastiaan89 yes I have run that and that's ok. I can't run anything to do with artisan though.

Remove the "vendor" folder and "composer.lock" and run:

composer install

Thank you both but it was me.

I removed the

require __DIR__.'/../vendor/autoload.php';

and replaced it with the

$compiledPath = __DIR__.'/../vendor/compiled.php';

in error. That'll teach me to watch what I'm doing.

Hi - noob here and excited to participate! I've got the same fatal error, but I see in my autoload.php file I've got both the require and the $compiledPath statements mentioned above. I see that $compiledPath is not getting set (compiled.php doesn't exist), but that shouldn't be impacting me in development mode, right? What else can I look for? TIA

autoload.php should look like (I've removed the comments)

<?php

define('LARAVEL_START', microtime(true));

require __DIR__.'/../vendor/autoload.php';

$compiledPath = __DIR__.'/../storage/framework/compiled.php';

if (file_exists($compiledPath))
{
    require $compiledPath;
}

What is the exact error you are getting?

the message: PHP Fatal error: Class 'Illuminate\Foundation\Application' not found in /Library/WebServer/Documents/laravel/billSearch/bootstrap/app.php on line 14

My script differs: the $compiledPath item is specified as:

    $compiledPath = __DIR__.'/../../vendor/compiled.php';

I modified it to the script you gave me and still getting the same error. TIA.

have you run

composer dump-autoload -o

around line 14 in app.php is

$app = new Illuminate\Foundation\Application(
    realpath(__DIR__.'/../')
);

confirming line 14 in app.php is identical. Yes, I ran composer dump-autoload -o. Result:

Mark-Manley:laravel markmanley2$ php composer.phar dump-autoload -o
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20121212/mcrypt.so' - dlopen(/usr/lib/php/extensions/no-debug-non-zts-20121212/mcrypt.so, 9): image not found in Unknown on line 0
Generating optimized autoload files
Mark-Manley:laravel markmanley2$

Not sure if this matters, but I had to use "php composer.phar...". This makes me wonder if my environment is not set up correctly.

@markmanley

Firstly it looks like PHP Mcrypt extension isn't being loaded, either it isn't present or another error. Anyway, try installing it from here:

http://php-osx.liip.ch

Secondly, you just need to mv composer.phar to one of your executable directories. Open up your terminal and change directory cd to where composer.phar is currently. Then execute the following command.

mv composer.phar /usr/local/bin/composer

Thank you Gyan.

After doing a git reset --hard a few directories were deleted and I was facing precisely the same issue.

composer update --no-scripts saved me.

Gyan, I made the same mistake!

So I corrected the composer.json, then deleted composer.lock and the vendor folder, and ran "composer update" again. Worked!!!

Jonathan, "composer update --no-scripts" is acceptable while developing, but not acceptable on the production server, as you're missing out on a lot of speed optimization. The scripts referred to in the command generate optimized class loader files, and even allows more advanced functions like compiled classes.

Having the same issue each time I try to spin up and existing project on another machine.

@Gyan,

composer update --no-scripts

did the trick.

Thanks!

I tried composer update --no-scripts but it gives error

[Symfony\Component\Console\Exception\RuntimeException] The "--no--scripts" option does not exist.

For someone bumping into this issue. I had an older version of the artisan file that did not require the autoloader. Newer versions do.

You can try replacing your artisan file with a new one from the Laravel Github repo.

FatalThrowableError in ProviderRepository.php line 146: Class 'Dingo\Api\Provider\LaravelServiceProvider' not found

composer update --no-scripts - does not give an error but when I run my project it gives above error.

Please help!
