It appears you are passing the options incorrectly. According to the docs status and fulfillment_status are keyword arguments and should be passed as follows:
ShopifyAPI::Order.all( status: 'any', fulfillment_status: 'any')
Please note this will only retrieve the first 50 by default. API Docs.
You can set the limit to 250 using limit: 250; however you cannot retrieve any more than 250 records at a time so to truly receive all of them you may have to loop this process multiple times using an offset like since or updated_at_min
