meteor 1.3 - Unable to resolve some modules:"pixi.js"

Question

I am trying to use pix.js in meteor 1.3. In atmostphere it says:

Use the npm version instead, i.e. meteor npm install --save pixi.js

so I install by meteor npm install --save pixi.js instead. but when I start up my meteor app, I get this error:

Unable to resolve some modules:

"pixi.js" in
/Users/xuanxi/Desktop/bitbuckets/mindbitapp13/client/detail/game.js (web.browser) If you notice problems related to these missing modules, consider running: meteor npm install --save pixi.js

How can I resolve this?
