Assuming I created this Ember application last week:
ember new shop
cd shop
ember install:addon ember-cli-scaffold
ember g scaffold product name:string
The console tells me that this application uses Ember 1.10.0:
How can I upgrade this Ember application to Ember version 1.11.0?
The syntax has been updated to:
bower install ember#2.0.0 --save-dev --save-exact
@Sukima's answer will work fine, but you can also use the ember-cli command:
ember install:bower ember#<version>
In your case, upgrading to Ember 1.11.0 would look like this:
ember install:bower ember#1.11.0
Sukima
Update the version in your bower.json file and run
bower install
From ember-cli 2.11 version, ember is served from npm package, so you need to update ember-source version number in package.json
"ember-source": "~2.11.0"
