title: Not running at local when "npm run serve" command in vue project
body: <p>I was trying to make some app with vue and installed npm command.</p>
  <p>when I run &quot;npm run serve&quot; command, I get the following messages.
  It seems that I was supposed to run app at &quot;http://localhost:8080/&quot; and was able to access sample pages, not like &quot;x86_64-apple-darwin13.4.0:&quot; stuff.</p>
  <p>is it possible to solve this with changing config file or something ?</p>
  <pre><code>App running at:
    - Local:   http://x86_64-apple-darwin13.4.0:8080/
    - Network: http://x86_64-apple-darwin13.4.0:8080/
  
    Note that the development build is not optimized.
    To create a production build, run npm run build.
