css-loader,sass-loader等编译失败的原因

一般出现下面的情况，是样式解析失败导致。样式解析失败是因为，依赖没装好或没装

解决办法： 看你使用的CSS语言是什么,是 常规的 或者 less 或者 sass

常规： 执行 npm install stylus-loader css-loader style-loader --save-dev

less：执行 npm install less less-loader --save-dev

sass：执行 npm install sass sass-loader --save-dev 或者（$npm intall sass-loader --save ; $npm install node-sass --save）

删除node_module: rm -rf node_module
重新安装： cnpm i

如果单独安装上面的某一步，还没解决问题，建议你都安装一下

完美！
