Fatal error: Class 'Illuminate\\Foundation\\Ap

问题:

I am getting following error when I open my site which is made using laravel 5

Fatal error: Class 'Illuminate\Foundation\Application' not found in C:\cms\bootstrap\app.php on line 14

I have tried removing vendor folder and composer.lock file and running composer install it's not working I tried running PHP artisan optimize but it shows error

Fatal error: Class'Illuminate\Foundation\Application' not found

Is there any way to solve this problem?

Edited: This problem aroused as soon as I used the php artisan make:model Page command which did create the model but then the above error gets displayed when I access the site Also If use the Larvel's Local Development Server no such problem arises only if I use wamp server

In my situation, I didn't have the full vendor dependencies in place (composer file was messed up during original install) - so running any artisan commands caused a failure.

I was able to use the --no-scripts flag to prevent artisan from executing before it was included. Once my dependencies were in place, everything worked as expected.

composer update --no-scripts

Just in case I trip over this error in 2 weeks again... My case: Checkout an existing project via git and pull in all dependencies via composer. Came down to the same error listed within the title of this post.

Solution:

composer dump-autoload
composer install --no-scripts

make sure everything works now as expected (no errors!)

composer update

Something is clearly corrupt in your Laravel setup and it is very hard to track without more info about your environment. Usually these 2 commands help you resolve such issues

php artisan clear-compiled
composer dump-autoload

If nothing else helps then I recommend you to install fresh Laravel 5 app and copy your application logic over, it should take around 15 min or so.

I just fixed this problem (Different Case with same error),
The answer above I tried may not work because My case were different but produced the same error.
I think my vendor libraries were jumbled,
I get this error by:
1. Pull from remote git, master branch is codeigniter then I do composer update on master branch, I wanted to work on laravel branch then I checkout and do composer update so I get the error,

Fatal error: Class 'Illuminate\Foundation\Application' not found in C:\cms\bootstrap\app.php on line 14

Solution: I delete the project on local and do a clone again, after that I checkout to my laravel file work's branch and do composer update then it is fixed.

回答5:

1.first open command prompt(cmd==>window+r) and go to the location where laravel
installed.

2.try==>'composer require laravel/laravel'

回答6:

For latest laravel version also check your version because I was also facing this error but after update latest php version, I got rid from this error.

回答7:

I had accidentally commented out:

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

in /public/index.php

When pasting in some debugging statements.
