问题

I'm trying to create a demo of ant-design for that I've installed ant-design and now when I'm hitting

npm start

I got this error

           dora: listened on 8000

I tried couple of solutions but since I'm new to ant-design it's getting hard to digest the concept. Is there anyone for me to fix this?

Thanks in advance :)
