在vue-cli建的vue项目中使用sass

前面已使用vue-cli新建了一个vue项目，参考  使用命令行创建一个vue项目的全部命令及结果

首先看下新建项目的页面和代码，有部分修改，可忽视，如下图：

   

然后我们在页面添加sass的代码：

修改完保存后立即就报错了：

    

在使用scss之前，我们首先需要安装相关的插件： 这里参考的是：链接（ vue 项目 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

Cached binary found at D:\nodejs\node_cache\node-sass\4.9.0\win32-x64-57_binding.node

> node scripts/build.js

Testing binary
Binary is fine

安装完重新启动项目，如下图，我们看到页面是可以正常显示了，用scss写的样式也起了作用哦 ：）

这里不同于参考链接的是，不需要配置参考文说到的webpack.base.config.js，可是也能正常使用了。

而安装上面的插件也是一次性就安装成功的，没有出现别的问题。

谁知道原因的可以留言哦，新手不是很懂这些配置文件。
