laravel 5.2: Command "optimize" is not defined

Question

I am working on laravel 5.2.

When I run composer install and composer update command, it show error:

[InvalidArgumentException] Command "optimize" is not defined.

Please let me know how to solved this problem.

Answer 1

This artisan command is deprecated. Simply remove it from your composer.json file.

Answer 2

"scripts": {
        "post-root-package-install": [
            "php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "php artisan key:generate",
            "php artisan jwt:secret -f"
        ],
        "post-install-cmd": [
            "Illuminate\\Foundation\\ComposerScripts::postInstall",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "Illuminate\\Foundation\\ComposerScripts::postUpdate",
            "php artisan optimize"
        ]
    },

remove php artisan optimize from post-install-cmd array and also from post-update-cmd than it will look like this.

"scripts": {
        "post-root-package-install": [
            "php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "php artisan key:generate",
            "php artisan jwt:secret -f"
        ],
        "post-install-cmd": [
            "Illuminate\\Foundation\\ComposerScripts::postInstall",
        ],
        "post-update-cmd": [
            "Illuminate\\Foundation\\ComposerScripts::postUpdate",
        ]
    },

working perfectly fine without any warning.

Answer 3

https://laravel.com/docs/5.6/upgrade says:

The previously deprecated optimize Artisan command has been removed. With recent improvements to PHP itself including the OPcache, the optimize command no longer provides any relevant performance benefit. Therefore, you may remove php artisan optimize from the scripts within your composer.json file.

Answer 4

Please note the after install or upgrade laravel following commands will be executed through composer.json file. Since 5.2 onwards optimize command has been depreciated. Please remove it.
