Permission issue for ionic

Error: EACCES: permission denied, open '/Users/in074811/.cordova/lib/npm_cache/cordova-ios/4.1.1/package/.npmignore'

Error during untar for /.cordova/lib/npm_cache/cordova-ios/4.1.1/package.tgz: Error: EACCES: permission denied, open '/Users/in074811/.cordova/lib/npm_cache/cordova-ios/4.1.1/package/.npmignore'

Error: Failed to fetch platform ios

Probably this is either a connection problem, or platform spec is incorrect.

Check your connection and platform name/version/URL.



Solution:
It may due to cache problem.

rm -rf ~/.cordova
