Migration Ionic3

Ionic Framework
#1

Iā€™m playing with the Ionic 4 beta and following the steps in the document, as a first step, try to load the css of my application, add it to the global.scss file and add my variables to the theme/variables.scss file, however, I get the error that the variable is not defined.

Also, create a new project like this:

ionic start myApp blank --type=angular

And when wanting to run the command ionic serve, ionic generate I receive the error

Cannot perform Ionic serve/watch for project type: angular.
#2

please check your system config.
ā€“ ionic info
ā€“ ng -v
ā€“ npm -v
ā€“ node -v

for ionic start myApp blank --type=angular check min needs for project env.
