Laravel 4：致命错误：在autoload.php中找不到类'Patchwork \ Utf8 \ Bootup'

I added "cviebrock/image-validator": "1.0.*" to require section of composer.json. After, I ran composer update, I am getting this Fatal error.

:::ERROR:::

:::END of ERROR:::

I need help in rectifying this fatal error.

This error seems to me like there is no patchwork/utf8 package installed.

See in your vendor folder whether the package exists or add in the require section in your composer.json file: "patchwork/utf8": "1.1.*" and then do composer update.

I was having the same problem because when I run php artisan db:seed --class=PostsTableSeeder

it started to remove laravel, symfony etc. I can't understand why?(may be my composer.json included at that time only "require": { "fzaninotto/faker": "1.3.*@dev" },)

So what I did, I updated my composer.json again and run composer update --dev. composer.json as

"require": {
    "laravel/framework": "4.2.*",
    "way/generators": "~2.0",
    "patchwork/utf8": "1.1.*",
    "fzaninotto/faker": "1.3.*@dev"
},

And that worked because it downloaded again everything.

I just commented the 'Patchwork\Utf8\Utf8ServiceProvider' in app.php and it worked

I am most certain you pulled your application from a git? If you take a closer look at your .gitignore file you would see that /vendor is one of the files/folders that git was told to ignore. You need to remove /vendor, composer.lock and composer.phar from .gitignore IF you're in development.

Also if you navigate to the /vendors folder via FTP or ssh, you will see that it only has folders that were outlined in your composer.json file under

"require": {

}

are the ones in the vendor folder.

Once you run composer update and composer install you should be fine.

I Solved It With composer dump-autoload and then composer update

After that it works But if you encounter more issue try to Delete the vendor folder or just rename it fo backup puporse incase it fails like mv vendor ve then

Delete composer.lock

Run the command composer clearcache (or clear-cache) Run composer install

Your good to go.

Dude, you just have to do this:

composer require patchwork/utf8
