× Package install failed, see above.
The Schematic workflow failed. See above.

also when applying this steps : 

npm config set @infragistics:registry packages.infragistics.com/.../
npm config set //packages.infragistics.com/npm/js-licensed/:username=YOUR_USERNAME
npm config set //packages.infragistics.com/npm/js-licensed/:email=YOUR_IG_EMAIL
npm config set //packages.infragistics.com/npm/js-licensed/:_auth=YOUR_IG_AUTH_TOKEN

Is the YOUR_USERNAME is user name on the account or the one shown on the access token page for npm feed.. e-mail I assume from the account.. 

Also is that the  problem that I install both Angular Schematics & Ignite UI CLI .. ? If it is how to uninstall them ? 

Thanks.
