QuickBooks API "Failed to open required file" - laravel

Question

I'm integrating QuickBooks API in my newly created laravel app. But I'm always stuck with an error of Failed to open required file. I've been searching for the same problem but none of them works. Is there anyone who have tried to integrate QuickBooks API to their laravel app ? Can you guide me on how do it ?
QuickBooks_Loader::load(): Failed opening required 'C:\wamp64\www\...\vendor\consolibyte\quickbooks/QuickBooks\Driver\.php' (include_path='.;C:\php\pear;C:\wamp64\www\...\vendor\consolibyte\quickbooks')
this is how I set up my qbo env variables.
QB_DSN= mysqli://root:#localhost:3306/omni_qbo
QB_TOKEN=AB11573209674XW53cTKF8xf5lY8vva2A4C8aMliPMWgWGUOl7
QB_OAUTH_CONSUMER_KEY= ABsW9nlMQEpjnzYNvl5ySx1FSqpaibMuJEe1DS0xMMt8bKpQoZ
QB_CONSUMER_SECRET=SxbO5CUvclrWWTFTnVCB1ZWvwk8TjqM67shCv3VP
QB_OAUTH_URL=http://localhost:8000/qbo/oauth
QB_SUCCESS_URL=http://localhost:8000/qbo/success
QB_SANDBOX=true
QB_USERNAME=DO_NOT_CHANGE_ME
QB_TENANT=12345
This is the controller sample code I copied from the link . I just followed the steps on how to integrate quickbooks api to laravel but still not working.
