뷰 폴더 복사하기 configureWebpack 에러

뷰 폴더 복사하기 강의를 듣고 있습니다. configureWebpack 를 추가하는 부분에서 에러가 발생합니다.

  configureWebpack: {
    plugins: [
      new FileManagerPlugin({
        events: {
          onStart: {
            delete: [
              '../backend/static/**',
              '../backend/templates/**',
            ],
          },
          onEnd: {
            copy: [
              { source: './dist/static', destination: '../backend/static' },
              { source: './dist/favicon.ico', destination: '../backend/static/img/' },
              { source: './dist/home.html', destination: '../backend/templates/' },
              { source: './dist/dashboard.html', destination: '../backend/templates/dashboard/' },
            ],
          },
        },
      }),
    ],
  },

위와 같이 따라서 코드를 입력했는데 다음의 에러가 발생합니다.

 ERROR  Error loading vue.config.js:

어떤 부분이 문제인지 모르겠습니다.

const { defineConfig } = require('@vue/cli-service');
