After updating to ember-cli 0.2.5 (same think with 0.2.4; 0.2.3 was ok), when i make a change to a file and save it, it keeps reloading my app at least 3 times for each save i do. Server's console shows file added... file added... file added... for all my app files each time, but my tmp folder is always empty. Also is seems that for each reload it tries to create a folder inside tmp folder, but it quickly removes it every time. The only file inside tmp folder is .metadata_never_index. Does this have to do with caching? Any help? I'm on yosemite.
I had this problem with watchman 3.1.0 (which is the version that Homebrew installs) so I upgraded to 3.1.1 and it seems to have been resolved.
You'll need to install it from source, but it's easy:
$ brew uninstall watchman
Then just
$ git clone https://github.com/facebook/watchman.git
$ cd watchman
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
Fingers crossed it seems to have worked so far (thank goodness, as it was driving me CRAZY).
