修改方法：

vue.config.js

css: { loaderOptions: { sass: { data: '@import "@/assets/styles/share.scss";' } } },

修改成

css: { loaderOptions: { sass: { prependData: '@import "@/assets/styles/share.scss";' } } },

data改成prependData

补充知识：Vue项目中使用jquery插件

1、引入jquery，并且在vue.config.js里配置

config.plugin('provide') .use(webpack.ProvidePlugin, [{ $: 'jquery', jquery: 'jquery', jQuery: 'jquery', 'window.jQuery': 'jquery' }])

2、下载hquery插件，放到public中

3、直接在组件里使用

备注：在vue里使用jquery改变样式的时候，一定要在setTimeout里调用
