Warn, don't error if a dependency is the wrong version.

[runspired]

Erroring out on missing dependencies is useful, erroring out on incorrect dependencies is a PITA. Often a dependency is mismatched because a new version is being trialed, and often it's a more recent version than the one in package.json. Warning would be much more useful.

If a new version is being trailed, the package.json should be updated. Or linked, both cases work correctly currently

The hard error is because the system is measurably in a bad state, I would encourage this invariant remain.

The current behavior breaks the ember-update command for exactly this reason..

EDIT: broke? ember-update appears to have been removed.

[stefanpenner]

this is actually why (one of the reasons) why we removed update.

I have plans to create a more standalone installer, as we have plans to do a more constraint based installation in the future. I hope to rectify the check+egg issue as part of that effort.

I would still like to support the "update an addon from a clean install" situation. Needing to install everything before you can get to work is frustrating, especially when that becomes

• manually modify package.json
• npm install
• ember g

If that was all you wanted to do for the day, it really cuts your time over being able to just do

• ember install

If that is something you want to work on, it would be greatly appreciated :P I don't forsee working on that for quite some time.. :(

I'm working on tools for helping maintain addon / app dependencies and facilitate faster scaffolding at the moment. Whether that will lead to wanting to work on a stand-alone installer, I don't know, but if it does I'll ping you.

@runspired did your work on this lead anywhere? I'm doing research before starting a similar effort and I want to make sure the project is based on current information
