You may need to clear the browser cache. It is possible that the compiled js that the browser is using is not the js that has most recently been compiled.

In Chrome you can see if the cached js is being used in the developer tools windows (ctrl + shift + i). In the size column it will say (from cache) instead of the actual size. You can then right click and clear the browser cache. ctrl + r to reload and the error should be gone.
