Angular 5经常性问题-Webpack无法编译一个简单项目

Question

I want to create and serve a ng app. The problem is that after following the installation of angular 5 (+ionic) I found myself have the same problem over and over again and I have no idea what is causing it. I don't really understand what is the issue but I cannot serve any angular app.

The way I can resolve this is by a complete format of C:\\ drive and reinstall anything from scratch. Last time I did it was 2 days ago. And before that 7 days ago.

This is all the stuff I get in the cmd.exe:
