在BoUoW上使用angular CLI创建的Angular 2上，ng服务失败

Question

I am running BoUoW in elevation mode and have installed @angular/cli and created a sample project using the new command.

When i try to run the app by npm start it fails by stating the error ng serve failed, and blames it on npm and node version issues or the app itself. npm and node version are the latest ones.

Any angular 2 expert advice or am i using the wrong boilerplate app?

Edit:

1. @angular/cli: 1.0.0-beta.32.3
2. node: 6.9.5
3. npm: 3.10.10

Edit 2: (error logs)

Edit 3: Steps to reproduce

Note i am using BoUoW on 14393.693 / 14.04.5 LTS

sudo n v7.5.0
npm install -g @angular/cli
ng new my-project
cd my-project
npm start

Answer 1

You've older version of node and npm. Current versions are:

node - v7.5.0
nam - 4.1.2

Please upgrade and try it again.
By the way, with Angular CLI, you can just ng serve. No need to use
npm start.
