How hard could it be to remove an add-on?
$ ember uninstall add-on The specified command uninstall is invalid. For available options, see `ember help`.
What does the trick is uninstalling the
$ npm uninstall add-on --save-dev
Alternatively, remove the package from
package.json and tell npm to remove “extraneous” packages:
$ npm prune
If you happen to have severe incompatibilities, go nuclear:
$ rm -rf node_modules tmp # edit package.json $ npm install
