Registry returned 404 for GET on http://ift.tt/1QfMLpR - ember install

I can't run my ember project any more, I have just cloned it from repository and works fine, with old build, but if I run 'ember build' command again get exceptions, generally it can't find some modules. I used combinations of commands

npm install
bower install
ember buld

but it seems npm install doens't do anything, now I try to run following command:

ember install -- NPM & bower dependencies

and get the 404 exception:

Registry returned 404 for GET on http://ift.tt/1QfMLpR - ember install

Any idea?
