Bower needs administrator privileges

[shreydesai]

There's an error with bower on Mac OS X where bower install doesn't work. It requires administrator privileges to install some files.

/usr/local/lib/node_modules/bower/lib/node_modules/configstore/index.js:54
                throw err;
                ^

Error: EACCES: permission denied, open '/Users/shreydesai/.config/configstore/bower-github.json'
You don't have access to this file.

It's also not super black and white – adding sudo to the command yields this error:

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.

You can however run a command with sudo using --allow-root option

But, adding the --allow-root flag to the command works, so this should be in the README if anyone runs into these troubles.
