Not sure if it helps, but I have done npm cache clean before creating a new project.

You are the best. 😉

@jgw96 in my case nothing was missed and everything was up to date. Please consider to mention in docs that Ionic can’t work anymore with apps structure when components folder is inside of app.

I found how to fix this issue (at least for my app, but maybe will be useful for somebody else). I had components, services, interfaces folders inside the app folder. After moving them one level up (to src) and changing imports, build passed successfully.

I have the same problem. Tried the things @agustin107 suggested, but no joy.

ionic v2.1.0 npm v3.10.8 node v5.7.1

UPDATE: I tried creating a new project and then it works. It was the existing project that didn’t play along even though I deleted node_modules and reinstalled again.

Please update npm to npm 3.x. You can follow the instructions here: https://docs.npmjs.com/getting-started/installing-node#updating-npm

Let me know if that fixes it for you!
