Why isn't a new Angular project created?

Question

Angular

I'm trying to create a new Angular project. Installed nodejs(4.2.6) first. Then npm(3.5.2). I write ng new test on the command line and I get this: Why is this happening?

Answer 2

1) You install the normal version of node 8+ and npm 6+
2) sudo npm install -g @angular/cli
3) ng new test will not work, because angular does not allow you to create a project with that name, so
4) ng new my-test
