Ember serve not working

Ember CLI
1

Hello to everyone,

I’m a noob in Ember and JS and I just started with Routes and Templates - Tutorial - Ember Guides. After installing nodejs, bower and watchman I try to run ember s and the following error is thrown.

valentin@valipc ~/super-rentals $ ember s
version: 2.2.0-beta.6
Livereload server on http://localhost:49152

This is the current configuration…

valentin@valipc ~/super-rentals $ ember -v
version: 2.2.0-beta.6
node: 0.12.9
npm: 2.14.10
os: linux x64

Any ideas why is this error present?

Hi There,

I’m also experiencing a similar error. I have installed watchman 4.3.0. ember 2.3.0 ember-cli 1.13.15

`ReferenceError: error is not defined

All requests will continue to fail with this message until you resolve
the underlying problem.  You will find more information on fixing this at

any help would be appreciated

This seems like a Watchman problem, have you tried uninstalling it and running ember serve?

@locks you are right, it seems to be caused by watchman. After removing watchman the server starts without any issues.

valentin@valipc ~/super-rentals $ ember s version: 2.2.0-beta.6 Could not find watchman, falling back to NodeWatcher for file system events.

I have also observed an occasional interference with sublime that seems to cause the NOENT error. If you are using sublime: quit sublime, then do “ember serve”, start sublime again.
