Unable to install spark

I have Laravel Spark installed in my project, and it works fine locally. I am trying to deploy it via CI and I am having issues.

include(/var/task/vendor/composer/../laravel/spark-aurelius/src/Providers/SparkServiceProvider.php): failed to open stream: No such file or directory

weirdly this only fails when doing php artisan migrate

composer.json has

"laravel/spark-aurelius": "*@dev",

and:

 "repositories":
        {
            "type": "path",
            "url": "./spark"
        },

This issue only occurs when I am deploying via CI. Locally the symlink is set up correctly. I have deleted vendor and done composer install but still not working.

I have seen this post but no help https://laracasts.com/discuss/channels/spark/class-laravelsparkproviderssparkserviceprovider-not-found
