[TYPO3-dev] Re: Composer installation add TYPO3 extension

[Philipp Wrann]

Aha, seems the package does have a composer.json but neither psr-4, nor psr-0 autoloading specified in it.

Fix:

Add the speficiation to your project root:

    "autoload": {
        "psr-4": {
            "Causal\\ImageAutoresize\\": "web/typo3conf/ext/image_autoresize/Classes/"
        }
    },

and run composer install again to regenerate autoloader
