I have successfully created a small application using ember-cli. I tried pushing it to gh-pages branch of my github repo but it shows error in browser console
As the comments already say: change the baseUrl in config/environment.js to the name of the GitHub repository you are pushing the app to. For example:
Your GitHub respository is called myEmberApplication and resides in
https://github.com/yourUsername/myEmberApplication.git
then the URL to this project's gh-pages would be
https://yourUsername.github.io/myEmberApplication
So in your case you have to change the baseUrl from / (default) to /myEmberApplication.
The reason why you have to do this is because ember-cli adds the header to your index.html file.
