[scarfase]

hello. I do all commands to run "Ext React KitchenSink". I need 6.7.x version.
node version: v10.16.0
npm version: 6.9.0
jre version: openjdk version "11.0.3" 2019-04-16
I have credentials for registry.
npm login --registry=http://npm.sencha.com --scope=@sencha
I clone project
git clone https://github.com/sencha/ext-react.git
change directory
cd packages/ext-react-kitchensink
run command
npm install
and got many errors.
