vendor class not found in laravel

Question

I use unisharp file manager in my project. on my local machine everything works fine, but on remote server it throws error [Symfony\\Component\\Debug\\Exception\\FatalErrorException] Class 'Unisharp\\Laravelfilemanager\\LaravelFilemanagerServiceProvider' not found in config/app.php everything's correct

    /*FileMananger*/
    Unisharp\Laravelfilemanager\LaravelFilemanagerServiceProvider::class,
    Intervention\Image\ImageServiceProvider::class,
    /*CKEditor*/
    Unisharp\Ckeditor\ServiceProvider::class,

there is directory unisharp in vedor(so all files and directories are there). when i try to run composer install/update i get this error again. so everything in its right place, but laravel doesn't see this class.

Answer 1

Try to comment those lines in config/app.php and run composer require unisharp/laravel-filemanager again.

You can't set up service providers before they are downloaded through composer.

Answer 2

你需要运行：

composer require unisharp/laravel-filemanager

Answer 3

Make sure your config/app.php unisharp providers is matched with the content in folder vendor unisharp composer.json check below:

Config/app.php

vendor/unisharp-composer.json

Answer 4

the solution is very easy :) just make sure you have this in your service provider:

 Unisharp\\Laravelfilemanager\\LaravelFilemanagerServiceProvider::class,

not this one:

 UniSharp\\Laravelfilemanager\\LaravelFilemanagerServiceProvider::class,
