Q:

ngCordova bower error - any ideas how to fix?

I've tried to make sure I'm using the latest version as my ngCordova media plugin isn't working for some reason.
I get this error:
npm WARN locking Error: EACCES, open '/Users/SubjectiveEffect/.npm/_locks/bower-e8debc5417026b57.lock'

I've no idea how to fix this.
Anyone any ideas?
Edit: I did some tidying up, uninstalled and reinstalled. I'm now getting this error when I try "bower install ngCordova"
"bower cached git://github.com/driftyco/ng-cordova.git#0.1.12-alpha
bower validate 0.1.12-alpha against git://github.com/driftyco/ng-cordova.git#*
bower ECMDERR Failed to execute "git ls-remote --tags --heads        git://github.com/driftyco/ng-cordova.git", exit code of #69 Agreeing to the    Xcode/iOS license requires admin privileges, please re-run as root via sudo.

Additional error details:

But if I try to run it with sudo I get told:
"bower ESUDO Cannot be run with sudo

Additional error details:
 Since bower is a user command, there is no need to execute it with superuser permissions.
If you're having permission errors when using bower without sudo, please spend a few minutes learning more about how your system should work and make any necessary repairs."

Any ideas?

A:

The error is stating problems accepting Xcode/iOS license agreement which is a dependency of cordova (to get iOS emulation working). 
I guess that Xcode has already been installed by npm/bower, you just need to open it for the first time (Cmd-Space, then type Xcode)  to accept the license agreement, then rerun bower install ngCordova.
If Xcode is not yet installed, it is probably less of a hassle to install it manually (see here for details), open it once and rerun bower install ngCordova.
BTW, ilj is right, it is usually a bad practice to run npm or bower under sudo. This leads to all sorts of worm cans.
