Browser sync failure on Centos 7

[dodozhang21]

Issue details

When I executed the following command

sudo ./node_modules/browser-sync/bin/browser-sync.js start --files "**/*.hbs, **/*.js, **/*.css" --port 80 --proxy localhost:3000 --no-ui --no-open

It fails with the following.

The same command works fine on my OS X.

Does anyone have any idea why this happens?
