I am trying to test the ember-select-2 component. It is advertised as very easy to set-up. According to the readme:
# install addon from npm repository
$ npm install ember-select-2
# install dependencies
$ ember g ember-select-2
Installing the add-on works:
» npm install ember-select-2
But installing the dependency fails:
» ember g ember-select-2
version: 0.1.2
Unknown blueprint: ember-select-2
The only thing I have been able to find is that ember-select-2 is an extraneous npm package (whatever that means)
» npm list ember-select-2
[email protected] .../test13
└── [email protected] extraneous
This is my ember-cli installatioon:
» ember --version
version: 0.1.2
node: 0.10.25
npm: 2.1.3
How did I manage to break such a simple how-to?
I did some research: extraneous just means that it is not in the package.json. Adding --save solves that. So that is just a warning, and not the source of my problem.
If you don't set the save flag, the package isn't added to your package.json file as a dependency it is only downloaded into node_modules, you will either have to add it manually or use the flag and have it save you a step.
--save: Package will appear in your dependencies.
--save-dev: Package will appear in your devDependencies.
--save-optional: Package will appear in your optionalDependencies.
When using any of the above options to save dependencies to your package.json, there is an additional, optional flag:
--save-exact: Saved dependencies will be configured with an exact version rather than using npm's default semver range operator.
More info can be found in the npm install docs.
