Using ember-cli addon

Question

I am trying to do a simple thing : use addons in the default project created with the command

ember new myproject

The initial project does compile: I can see the welcoming message on localhost:4200. Any addon I choose to add is installed the same way:

ember install theAddon

I can see the newly added addon in the package.json file. I have read that on build process ember will scan the dependencies (listed in package.json) and will create class instances for dependency which has the ember-addon keyword listed in their dependency file. So if I understand this correctly it is done automatically. Well when I run I always get

Uncaught Error: Assertion Failed: A helper named 'my-addon' could not be found.

For example one that I tried is

ember-radio-button

and it complains that it cannot find 'radio-button' helper

Answer 1

When installing an addon you need to restart the ember server. Installing an addon modifies the build environment.

After killing the server and restarting with ember s or ember server the addon can be used safely.
