Angular cli npm start failed

Question

I'm using angular-cli for my first angular 2 project, but it generates the error below when I use npm start command

Running without elevated rights. Running Ember CLI "as Administrator" increases performance significantly.
See ember-cli.com/user-guide/#windows for details.

Livereload failed on http://localhost:49156.  It is either in use or you do not have permission.

I check all my prerequise for my machine because I have, node v5.5.0, typings 1.3.2, but it still generates the same error.

What I missed?

Thank you in advanced!

Edited : I run the npm start command this morning, and it has the following error:

The Broccoli Plugin: [BroccoliTypeScriptCompiler] failed with:
Error: EPERM: operation not permitted, symlink

I hope you are through with ng init command so all the node modules are installed, Can you add the info about task which gets executed when you run `npm start` and also what is the version of angular cli you have? — Madhu Ranjan, Aug 09 '16 at 14:08
Are you sure the port 49156 is available ? You can try to access URL http://localhost:49156 to check. — Nicolas Henneaux, Aug 10 '16 at 06:49
@NicolasHenneaux, it returns `{"tinylr":"Welcome","version":"0.2.1"}`. And according @eg16, I run the command as Admin, and the port `4200` is available, but when I check into console of dev tool, it has `zone.js:323 Error: Error: XHR error (404 Not Found) loading http://localhost:4200/system-config.js(…)` as error, so how can I solve this? — Radonirina Maminiaina, Aug 10 '16 at 07:04
You have probably another process running. Try to close all the other ng serve and restart a new one. — Nicolas Henneaux, Aug 10 '16 at 07:09
Thank you guys, it works now! I restart my computer to make sure that all process stop. — Radonirina Maminiaina, Aug 10 '16 at 07:41

From the question answer, it was related to another process using the port 49156 which is required by Angular CLI for auto reloading. To be sure, there is nothing using the port you can request the URL http://localhost:49156/. If you do not find the process, a restart can solve the problem.

What do you mean ? – Nicolas Henneaux Aug 11 '16 at 10:22
This 49156 port is not the serve port, i think, it is a test port – Radonirina Maminiaina Aug 11 '16 at 11:49
It is the port used to handle reloading of the page such that when you modify a file, the cli build and once ready it triggers the reload of the browser using this port. – Nicolas Henneaux Aug 11 '16 at 19:36
