Laravel Lumen Memcached not found

Ok, I just started with Lumen and I'm trying to use the Auth, but a call to either Auth::check or any other function of Auth.. leads to the below Error Fatal error: Class 'Memcached' not found in vendor\illuminate\cache\MemcachedConnector.php on line 52. I don't want to use Memcached never used it before.

I disabled it in the .env file and set the CACHE_DRIVER and SESSION_DRIVER to array, but still shows the same error.

I decided not to use Auth again and to manually handle my authetication with sessions/tokens, but enabling the MiddleWare StartSession results to the same error.

$app->middleware([
 // 'Illuminate\Cookie\Middleware\EncryptCookies',
 // 'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
  'Illuminate\Session\Middleware\StartSession',
 // 'Illuminate\View\Middleware\ShareErrorsFromSession',
 // 'Laravel\Lumen\Http\Middleware\VerifyCsrfToken',
]);

Please I'd be so glad if anyone can really help me out here

EDIT

After going A little Deep in the framework I Hard Coded the session driver name in the SessionManager Class within the method getSessionConfig

public function getSessionConfig()
{
    $this->setDefaultDriver("cookie");//I added this line
    return $this->app['config']['session'];
}

It works though but not a good way of doing things. There is no config file, i believe all configurations are written in .env file, but i really don't know why the session_driver and cache_driver is defaulted to memecached even after changing it in the .env and then ran composer dump-autoload ... Lumen :(

EDIT This is my .env file

APP_ENV=local
APP_DEBUG=true
APP_KEY=SomeRandomKey!!!

APP_LOCALE=en
APP_FALLBACK_LOCALE=en

DB_CONNECTION=mysql
DB_HOST=localhost
DB_DATABASE=test
DB_USERNAME=root
DB_PASSWORD=

CACHE_DRIVER=array
SESSION_DRIVER=cookie
QUEUE_DRIVER=database

I already have this line uncommented in my bootsrap/app.php

 Dotenv::load(__DIR__.'/../');

My DataBase configuration works perfectly so the .env file is loaded quite alright.

This issue resolved when i installed this package so try at least

First i tried this and it works fine

CACHE_DRIVER = array

but then thought about what is memcached

Then i tried this and it works fine without changing driver memcached

apt-get install php-memcached

yum package manager or in Amazon Linux.

yum install php-memcached -y

I spent 3 hours on this problem today. With the help of the post of demve in this topic, I found the solution. Very simple! I hope it won't affect me later in my development.

Just to it, in the .env file :

CACHE_DRIVER=array
SESSION_DRIVER=array
QUEUE_DRIVER=array

Ok, I make an UPDATE because I was faced with a new problem about the session. In fact, when you set the previous parameters, your session won't be persistent, like said in the documentation: array - sessions will be stored in a simple PHP array and will not be persisted across requests.

So I have to change it, always in .env a file like that :

SESSION_DRIVER=cookie

With a var_dump(Session::all()); I now can see the whole values of my session

This happens if your .env file is owned by another user than the one trying to run the artisan command.

If you have a new lumen installation, you must rename .env.example to .env . So it can read your configurations!

in your .env file, you can also use CACHE_DRIVER=file instead of CACHE_DRIVER=memcached

#With this:-

Check if memcached is installed, if not install it by running:

apt-get install php5-memcached

For me, the issue was that I used the php-7 branch of homestead repository which does not have PHP memcached ready.

Dotenv::load(__DIR__.'/../');

in my bootstrap/app.php and the .env file started working.

I had a similar problem now, I couldn't track it down but my guess is that it has something to do with the fact that the defaults configurations are stored in the vendor/laravel/lumen-framework/config folder, the DotEnv::$inmutable setting and the artisan serveserver.

The solution that worked for me was:

  1. Add in bootstrap/app.php the following: Dotenv::makeMutable(); Dotenv::load(__DIR__.'/../'); Dotenv::makeImmutable();

  2. in the .env file, set all the configuration to "basic drivers" (array, file) even if you are not going to use them, because you w

Make sure not to get caught out by your .env file not being loaded, which by default it's commented out in Lumen. So if you are specifying a different cache driver in your .env, do the following.

Note: If you are using the .env file to configure your application, don't forget to uncomment the Dotenv::load() method in your bootstrap/app.php file.

You may need to restart your server, especially if you're using php artisan serve.

Lumen doesn't appear to pick up .env changes per-request.

I had exactly the same issue - trying to use file cache, but received errors regarding Memcached - restarting the server reloads the .env file.
