vue项目npm run build打包 本地打开出现空白页 Tip: built files are meant to be served over an HTTP server

npm run build打包好出现如下警告：

Tip: built files are meant to be served over an HTTP server.
Opening index.html over file:// won’t work.

打开config文件夹下的index.js文件，把build里的assetsPublicPath由 ‘/’ 改为 ‘./’ 即可
找到项目所在目录，进入下图49行所示的文件目录 dist文件夹下的 index.html，双击就会在浏览器打开项目
