Ember and/or npm use the same global /tmp directory. When two apps have the same lib, there may be a situation where the current user will not have rights to overwrite a new folder or file.

You have to set TEMP env variable for the user. In your deploy.rb file, add:

set :default_env, {
  'TEMP' => '/tmp/{app_name}_tmp'
