Error With Polymer Build

I am triying to learn how to use the new app-toolbox. In local, works fine; but when I use: polymer build I get these errors: C:\Users\Marcos\Documents\poly2>polymer build i

Solution 1:

I got the same problem. Deleting npm-cache at C:\Users\%USER_NAME%\AppData\Roaming\npm-cache and re-installing nodejs and polymer-cli fixed this for me. Currently, I'm using Windows 10 with nodejs v4.4.5, npm v2.15.5 and polymer-cli v0.11.0 (I notice that they've just updated polymer-cli from v0.10.0 to v0.11.0)

Hope this help.
