Vue JS 构建不导入 CSS 文件

Question

My CSS code that I imported into my Vue project and runs in the "npm run serve" section does not work on my server after "npm run build". What could be the reason for this? When I open the index file in the dist file on the local computer, it says CSS is missing, it does not say any error on the server.

main.js

import Vue from 'vue'
import App from './App.vue'
import VRouter from './router'
import VStore from './configurations/storeConfiguration'
import V18n from './configurations/languageConfiguration'

// Special CSS Library ( UA )
import "./assets/scss/ua.css";

The CSS file that appears appears in the development environment. However, it does not appear in the server environment.
