基于vue-cli2.0的MPA项目，需要配置骨架屏。
骨架屏配置文件webpack.skeleton.conf.js：
/**

在 webpack.prod.conf.js 中 配置usePostCSS=true开启CSS文件分离，此时会报错：
ERROR in ./static/css/life.css
Module build failed: EntryModuleNotFoundError: Entry module not found: Error: Can't find options with ident 'ref--5-3'

ps:注释掉skeletonWebpackPlugin插件引用就ok了，或者关闭postcss也OK了。应该还是骨架屏导致CSS代码分离失败，一时找不到原因。求帮助
我也遇到这个问题了,目前的解决方法是把webpack.prod.conf.js里面的 extract和usePostcss改为false
