Step missing in installation?

[averied]

OK so i follow the instructions in the main page:

Usage
This is a project template for vue-cli. It is recommended to use npm 3+ or yarn for a more efficient dependency tree.

1. $ npm install -g vue-cli

2. $ vue init pwa my-project //AT THIS POINT I GET AN ERROR SAYING THAT I NEED TO "npm install -g @vue/cli-init". Is this step missing in the docs? o am I doing something wrong?.

Also when doing init pwa, there is a warning about

npm WARN deprecated coffee-script@1.12.7: CoffeeScript on NPM has moved to "coff
eescript" (no hyphen)

$ cd my-project
$ npm install
$ npm run dev
