无法将超级分层结构网络连接到资源管理器

我在ubuntu 16.04 VM上设置了一个光纤网络（v1.1.0） . 我想将该网络连接到超级分类帐浏览器，以查看不同对等方的块和分类帐副本，我正在使用此https://github.com/hyperledger/blockchain-explorer repo .

我尝试构建资源管理器时的编译警告

nik@nik-VirtualBox:~/fabric-samples/blockchain-explorer/client$ npm run build

 hyperledger-explorer-client@0.3.0 build /home/nik/fabric-samples/blockchain-explorer/client

The project was built assuming it is hosted at the server root.
You can control this with the homepage field in your package.json.
For example, add this to build it for GitHub Pages:

  "homepage" : "http://myname.github.io/myapp",

The build folder is ready to be deployed.
You may serve it with a static server:

  npm install -g serve
  serve -s build

我尝试运行浏览器，我可以看到日志，但是当我启动http://localhost:8080时，它显示错误
