I started my first project with ember cli and I noticed that the live reload isn't working. When I start the development server, I get multiple error messages (see below). Changes to the code base are only available after a restart of the server.

$ ember server
version: 0.1.2
Livereload server on port 35729

Any idea what could cause this issue? It is quite annoying to restart the server for every change. Thank you for your suggestions.

  • Is this on windows 7/8 or OSX or linux? What if you upgrade to ember-cli 0.1.3 and try this again? – Toran Billups Dec 04 '14 at 04:32
  • have you tried rebooting? sometimes my live reload likes to stop functioning – tr3online Dec 04 '14 at 05:06
  • I am running ember-cli on OSX. I get the same error with 0.1.3. – neurix Dec 04 '14 at 05:08
  • It seems that the errors were generated by a corrupted js file in the browser cache. By coincident, I deleted the whole browser cache and the live reload works again. – neurix Dec 05 '14 at 05:17
  • Are you using Sublime? If so adding "folder_exclude_patterns": [".svn", ".git", ".hg", "CVS", "tmp/*"] to User Settings may help – David Douglas Feb 20 '15 at 15:47
  • @neurix is this still relevant? both `0.2.x` and `1.13.x` seem to be working for me. – locks Jul 09 '15 at 05:14
  • @locks Thank you for checking in. The problem isn't relevant anymore. I think some file got corrupted (but after 7 months I am not sure anymore). – neurix Jul 09 '15 at 16:23

The error is essentially caused by FSEvents watching too many files. If you're using Sublime Text, try excluding node_modules/, tmp/, and dist/ from your project (add them to the folder_exclude_patterns array in your Sublime user preferences).

If you're not using Sublime, or if doing so doesn't fix the issue, try upgrading your version of Node and version of ember-cli to the latest versions, as well as installing watchman using brew install watchman if you have Homebrew installed/are on OS X (as the latest versions of ember-cli no longer rely on FSEvents.

  • Nice necro answer, I was really confused reading it was a new project with ember 1.7 there for a second after it popped into my feed. ;) – Kit Sunde Aug 20 '15 at 02:38

Add this parameters(liveReload and Watcher) to the file

/.ember-cli
and this will end with something like this: 
{
  /**
    Ember CLI sends analytics information by default. The data is ...
  */

  "disableAnalytics": false,
  "liveReload": true,
  "watcher": "polling" 
}
/* Pooling, this is where the magic come, allow to edit file in the host and outside(EX: Virtual machines and servers relate) */
