Current behavior:
When running 'ionic start my-app' it errors on not finding npm and quitting.

    [INFO] Installing dependencies may take several minutes!
    ✖ npm install - failed!
    [ERROR] Command not found: npm

Expected behavior:
Using yarn when npm isn't available and yarn is. OR not crashing but skipping installing packages when no npm installation is detected, and allowing the user to manually install packages via his/her choice of package manager.

Perhaps in an addition to:
ionic config set -g yarn true

Now the following, as of my post, is needed for ionic to use yarn:
ionic config set -g npmClient yarn

Definitely understandable.
@jgw96 Can you please move this to the ionic-cli repo?

@IncognitoCore This isn't _quite_ documented yet, but please try enabling yarn with:

$ ionic config set -g yarn true

Let me know if you have any issues with it.

Awesome! That works ;) Thanks for the fast response!

ionic config set -g yarn true
[OK] yarn set to true in ../../.ionic/config.json!

@IncognitoCore The Ionic CLI will make use of yarn now instead of npm for package management operations. Do you think it's wise to try to detect yarn and automatically enable it if it exists and npm does not? Did you uninstall npm? 😆 I thought it came with node generally.

@dwieeb I'm not sure actually. I installed yarn via homebrew brew install yarn and it looks like that uninstalled npm.
