致命错误：在生产中安装composer之后找不到类'LaravelLocalization'

Question

It's been 3 days since I'm working on translating my site, so I installed LaravelLocalization:

I did everything working in local, then I pushed it in production and executed:

composer install --no-interaction --no-dev
php artisan clear-compiled
php artisan optimize
composer dump-autoload -o
php artisan route:cache
php artisan config:cache

Now, all the "php artisan commands fail with:"

 [Symfony\Component\Debug\Exception\FatalThrowableError]  
 Fatal error: Class 'LaravelLocalization' not found       

In this case, in the composer install script, it fails in:

php artisan clear-compiled

I tried to run:

php artisan cache:clear
php artisan route:clear

But without any results...

Any ideas??? This is not the first time I get this kind of stuff, but I may say that this it's a pain in the ass :(

EDIT:

In my routes.php,

I deleted this line:

Route::group(['prefix' => LaravelLocalization::setLocale(), 'middleware' => ['localeSessionRedirect', 'localizationRedirect']],

around all my routes, and now composer install works.

But it doesn't solve my issue, because as soon as I put it back, I still get the same error :(

Answer 1

I resolved it removing the line:

Route::group(['prefix' => LaravelLocalization::setLocale(), 'middleware' => ['localeSessionRedirect', 'localizationRedirect']], 

in my file routes.php

run again

composer install

and finally

php artisan config:clear
php artisan route:clear

What I don't know is why it happened, and if there is a way to prevent it...
