Hello dear Aurelia users,  
I’m brand new to the platform and first timer with Aurelia. However, whenever I try to do something, as even the Hello World and keeps on giving me errors, especially when installing aurelia-cli or when I try to run it. I have tried with --watch and -save but it doesn’t help. If someone has an idea how to fix it, please reply to me

Ignore those audit messages for now. What happens when you just run the application:

```auto
$ webpack-dev-server

```

Something wrong with webpack.config imho
