ionic framework - cordova fails with exit code 2 -

i building ionic/angularjs/phonegap app. new front end development. have package.json , bowser.json. in package.json, after installing packages, run "bower install" install bower dependencies. able run python server in www , see app in chrome. not able run in android emulator. can please guide me?

edit

i realized after posting question ionic ships angular , should use that. don't need bootstrap ionic framework need. need underscore. clean up. don't think of related error.

here error after running "cordova build":

@givanse - answered own question, if have platform dependencies(meaning code not want loose in platform/android), clean build, did:

rm -r platforms/android/ant-build rm -r platforms/android/assets 

all now. thanks.
