Getting Errno::ENOENT: No such file or directory - chdir when running rake ember:install

I want rails to serve my ember front, and I'm using: ember-cli-rails

I set my config/initializers/ember.rb as:

EmberCli.configure do |c|
  c.app :item_tracking
  c.app :frontend, path: "~/myApp/client/dist"
end

and config/routes.rb as:

Rails.application.routes.draw do
  mount_ember_app :frontend, to: "/"
end

When I run rake ember:install, I got:

Errno::ENOENT: No such file or directory - chdir

I'm sure I build the entire ember in ~/myApp/client/dist, and I guess the problem is caused by this path, can someone give me a suggestion?
