Cloud 9 and Grunt.js

问题

I'm running grunt.js on Cloud9. Most everything is working correctly, except when I try to set this option:

'watch: {
    options: {livereload:true},'

If I add that, the terminal states: 'Fatal error: listen EACCES'

I'm guessing I need to use the sudo command to run that and since c9 doesn't let you run sudo, the command fails.

But why is livereload a feature that requires permission? And is there any way around it?
