Update from Laravel 5.5 to 6

Question

I am trying to update the Laravel5.5 project to 6. What I tried is first describing the package update

"php": "^7.2",
"ext-SimpleXML": "^7.3",
"barryvdh/laravel-ide-helper": "^2.6",
"doctrine/dbal": "^2.10",
"fideloper/proxy": "^4.0",
"jeroennoten/laravel-adminlte": "^2.0",
"laravel/framework": "^6.0",
"laravel/tinker": "~1.0",
"laravelcollective/html": "^6.0",
"maatwebsite/excel": "^3.1",
"laravel/ui": "^1.1",
"phpoffice/phpspreadsheet": "^1.9",
"phpoffice/phpexcel": "dev-master"

I get error

Call to undefined function str_slug()

So install this library

composer require laravel/helpers

Then this error came out

JeroenNoten \ LaravelAdminLte \ ServiceProvider :: class, not found

Reinstalling adminLTE doesn't help, commenting out and reinstalling doesn't work, I'm stuck and want help

I need help

You are using the wrong serviceprovider for adminlte package. Actually, you don't need to add it service provider to app.php, Laravel will autoload it. — Elias Soares, Dec 04 '19 at 00:59
@EliasSoares I knew it was added automatically, so I tried it but it didn't work — su3158, Dec 04 '19 at 01:15
"it didn't work", what didn't work? what actually happened and what was your expectation of what would happen? — lagbox, Dec 04 '19 at 01:32
@lagbox this is JeroenNoten \ LaravelAdminLte \ ServiceProvider :: class — su3158, Dec 04 '19 at 02:49
if you had cached the config previously you will need to delete the cached config, which it shouldn't be cached in development anyway ... and what is with the spaces between everything? — lagbox, Dec 04 '19 at 02:50

Open the composer.json file of your project (The configuration file of Composer) and change the Laravel framework . (Notice the caret, Laravel 6 makes use of semantic versioning scheme).

you are recommended to first upgrade your project to 5.8 then again upgrade to v6.

Next, save your composer.json file and run the following command:

$ composer update

Before you upgrade your project to v6, make sure your upgrade your PHP version from 7.1 to at least 7.2.

starting from December 2019, PHP 7.1 will not be maintained.

Remove space in config/app.php file:

    JeroenNoten\LaravelAdminLte\ServiceProvider::class,

],
