howdy, i've been trying to get pixi plugins to work in my project. i placed the pixi-display.js file in my scripts folder and included the script in my html just under pixi.js with the correct path. i'm getting an error in console: "PIXI.DisplayList is not a constructor".. something like that... i figured i'd try to build pixi and have the plugins included in the main file though i'm not sure it's possible. it's my first time using npm. i downloaded the pixi.js repository and from inside it's directory ran 'npm install'. npm gives me many "warn" is that normal? any assistance would be so greatly appreciated. i just want pixi with all plugins so i can experiment. i'd love to fully understand how to build it .
