vue打包问题：Tip: built files are meant to be served over an HTTP server.

npm run build之后，出现提示：Tip: built files are meant to be served over an HTTP server. Opening index.html over file:// won't work.

npm run build的时候 , 因为vue-cli的默认配置中, publishPath是用绝对目录, 所以dist文件夹里的文件必须放在服务器的根目录, 如果你想本地打开的话, 可以在npm run build完成之后执行以下命令:

npm install -g http-server
