你好，A simple app server using STS，这个demo我怎么启动不了

npm WARN enoent ENOENT: no such file or directory, open 'C:\。。。\package .json'

XMLHttpRequest cannot load http://localhost:3000/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

var appServer = 'http://localhost:3000'; var bucket = 'js-sdk-bucket-sts'; var region = 'oss-cn-hangzhou';
