当我尝试构建 vue3 组件库时，如何解决这个问题？

Question

我正在尝试使用 vue-sfc-rollup 创建一个 vue3 组件库，准备好我的组件后，当我运行 npm 运行 serve 然后它运行良好，但是当我尝试构建 (npm 运行 build) 时，我收到了这个错误。不知道怎么解决。

显示 scss 代码错误。错误图像下方也给出了代码

请指教

代码如下

rollup.config.js:

import fs from 'fs';
import path from 'path';
import vue from 'rollup-plugin-vue';
import alias from '@rollup/plugin-alias';

const esbrowserslist = fs.readFileSync('./.browserslistrc')
  .toString()
  .split('\n')
  .filter((entry) => entry && entry.substring(0, 2) !== 'ie');

// Extract babel preset-env config, to combine with esbrowserslist
const babelPresetEnvConfig = require('../babel.config')
  .presets.filter((entry) => entry[0] === '@babel/preset-env')[0][1];

// Export config
export default buildFormats;

我已经解决了这个问题。我做了什么。

$ npm install --save-dev rollup-plugin-scss

然后我在roleup js中添加了一些代码

import scss from 'rollup-plugin-scss';
//....
const baseConfig = {    
  plugins: {
  ....
    postVue: [
     .......
      scss()  // added this
    ],
   ....    
  },
};

当我尝试构建 vue3 组件库时，如何解决这个问题？

How can I fix this issue, when I trying to build a vue3 component library?

npm

vue-component

vuejs3
