使用/deep/修改样式不生效的问题解决方案

首先写/deep/会报错

in ./src/views/dashboard/index.vue?vue&type=style&index=0&id=106c86ed&lang=sass&scoped=true&

Syntax Error: SassError: Expected newline.

因为sass版本号太高造成问题

1. 在packjson查询自己当前sass版本号是否高于7.0.0,

2. 卸载当前的sass
   npm uninstall sass-loader

3. 安装 npm install sass-loader@7.0.0

4. 安装低版本的sass-loader需要引入node-sass依赖来支持,请执行下列代码 npm install node-sass

5. 这时候你发现又报错了
   

6. 不着急 输入 npm install node-sass@latest
   又报错了,emmmm…网不好
   

7. 换个淘宝镜像继续下载 cnpm install node-sass@latest

然后就解决啦!!!
