Error running aurelia-cli app

Question

I've been trying to start a new Aurelia project using the CLI. Unfortunately I've been unable to get it running, as detailed below.

Steps to reproduce:

1. au new
2. Give name & choose Typescript
3. cd into directory
4. au run

Results in the following output/error

$ au run

Environment:

• NPM version: 4.5.0
• Aurelia CLI version: 0.27.0

Answer 1

The Aurelia CLI does not support NodeJS 4.x. You must have at least NodeJS 6.x.
