Jquery 404 error on Windows

I setup my hugo site on Windows 10. I followed the quick startup guide. After I ran

hugo server -w

The site started without any error. But when I access http://localhost:1313, I got an ugly website. I checked the developer console, and I saw many javascript and css 404 error.

Should I installed those JS myself?

Thanks.

Can you send the screenshot of developer console?

You should look at the HTML page to check the path to the files. If some paths are not correct they need to be fixed in templates.
