I had this issue when deploying my app to Google App Engine. I found that by moving "nunomaduro/collision": "^2.0" from "require-dev" to "require" in my composer.json fixed this problem.

Solution 2:[2]

  • move nunomaduro/collision: ^2.0 from require-dev to require in composer

If that doesn't solve the problem, try

  • deleting the composer.lock file
  • uploading the project again without this file (it solved it for me)

If your project is not running on production, set the APP_ENV to dev or something different than production. The migration and seeds should work.

Solution 4:[4]

Inside of your composer.lock ,

Move "nunomaduro/larastan": "^0.3.0", to "require" from "require-dev" .

then run composer install

this worked for me

In your case the problem was that after running composer install --no-dev, php artisan package:discover is run automatically.

Whenever php artisan command fails, it tries to use the class NunoMaduro\Collision\Adapters\Laravel\CollisionServiceProvider for error handline which is only installed when laravel development packages are used. As you can see in this composer.json, collision is in the require-dev group.

    "require-dev": {
        "nunomaduro/collision": "^6.1",
    },

The problem can be solved by:

  • moving the dependency to the require section
  • or figuring out what causes the artisan command error.

In my case, it was either outdated php files or permission issues in the bootstrap/cache directory.
