Ionic build error - module.js:340

Hi,
I'm trying to execute the build command and I receive the following error:

module.js:340
throw err;
^

Error: Cannot find module 'C:\Users\EF\AppData\Roaming\npm\node_modules\
cordova\bin\cordova'
at Function.Module._resolveFilename (module.js:338:15)
at Function.Module._load (module.js:289:25)
at Function.Module.runMain (module.js:457:10)
at startup (node.js:138:18)
at node.js:974:3

When I'm using the phonegap command everything works perfectly...
Any suggestions?

Thanks
