Symfony bundle error NotFoundException: Attempted to load class "FullCalendarBundle" from namespace "Toiba\FullCalendarBundle"

Question

I have coded a webapp in php 7+ and symfony 3.4, everything works fine in dev mode.

Then I tried this command :

composer install --no-dev

and this error occured :

[RuntimeException] An error occurred when executing the ""cache:clear --no-warmup"" command:

Fatal error: Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "FullCalendarBundle" from namespace "Toiba\FullCalendarBundle". Did you forget a "use" statement for another namespace? in F:\wamp64\www\justdrive\app\AppKernel.php:15

I have tried to modify this :

"psr-4": {
    "AppBundle\\": "src/AppBundle"
},

to this :

"psr-4": {
    "": "src/"
},

and then execute this command :

composer dump-autoload

but I still get the same error after the first command I mentionned.

here is the bundle in my composer .lock

Here is the bundle in appkernel.php

public function registerBundles()
    {
        $bundles = [
...
new Toiba\FullCalendarBundle\FullCalendarBundle(),
...
];

Can you please help me?

Answer 1

Thanks to @Cerad and @Frankich I was able to get it working.

I had to execute

composer require toiba/fullcalendar-bundle

to install it proprely and then the

composer install --no-dev

command woked nicely!

Thank you very much.
