I followed the instructions from here. It seems the Build failed with the Javascript JQuery Typings. I encountered the same issue from this post. Is there any workaround?

$ ng serve                                                                                                                                                                 127 ↵

It seems the solution given here works. This issue is resolved when the tutorial is updated, because anyone who will follow the tutorial will encounter the same issue.

npm install --save-dev @types/jquery@3.2.7
