** Angular Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200/ **

I opened browser on http://localhost:4200/ and only get" Cannot GET / "
tried "npm run postinstall" and still having the same issue.

Hi @alanwongct,

We released an update today (version 4.2), can you verify whether you still are having the issue on the new version?

Also, I'm not sure you have to run ng serve with sudo. I've not tried hosting the Navigator on Linux but on OSX I know it can be served without the sudo command. This is probably not the issue but it's worth noting regardless.

Closing due to lack of activity. I'm happy to reopen it if the problem is still occuring.
