前面已使用vue-cli新建了一個vue項目，參考 使用命令行創建一個vue項目的全部命令及結果
首先看下新建項目的頁面和代碼，有部分修改，可忽視，如下圖：
然后我們在頁面添加sass的代碼：
修改完保存后立即就報錯了：
在使用scss之前，我們首先需要安裝相關的插件： 這里參考的是：鏈接（ vue 項目 使用sass ）
$ npm install node-sass --save-dev
> node-sass@4.9.0 install F:\05 poverty alleviation project\poverty\node_modules\node-sass
> node scripts/install.js

Testing binary
Binary is fine

安裝完重新啟動項目，如下圖，我們看到頁面是可以正常顯示了，用scss寫的樣式也起了作用哦 ：）
這里不同於參考鏈接的是，不需要配置參考文說到的webpack.base.config.js，可是也能正常使用了。
而安裝上面的插件也是一次性就安裝成功的，沒有出現別的問題。
誰知道原因的可以留言哦，新手不是很懂這些配置文件。
