Svelte Swiper导致意外的@ in /swiper/swiper.scss

Question

所以，我正在使用svelte构建一个站点，我正在使用swiper来实现其中一个功能，但我得到了这个错误，声明为[!] Error: Unexpected character '@' (Note that you need plugins to import files that are not JavaScript)。这说明我不能在scss中使用@import指令，从我的研究中我发现我的svelte应用程序不支持scss文件。rollup.config.js中需要Scss预处理器。但是plot twist，我有scss支持，我在我的项目中使用scss，而不是普通的css。这是我的rollup.config.js

import svelte from 'rollup-plugin-svelte';
import commonjs from '@rollup/plugin-commonjs';
import resolve from '@rollup/plugin-node-resolve';
import livereload from 'rollup-plugin-livereload';
import { terser } from 'rollup-plugin-terser';
import sveltePreprocess from 'svelte-preprocess';
import typescript from '@rollup/plugin-typescript';
import css from 'rollup-plugin-css-only';

const production = !process.env.ROLLUP_WATCH;

function serve() {
    let server;

    function toExit() {
        if (server) server.kill(0);
    }

    return {
        writeBundle() {
            if (server) return;
            server = require('child_process').spawn('npm', ['run', 'start', '--', '--dev'], {
                stdio: ['ignore', 'inherit', 'inherit'],
                shell: true
            });

            process.on('SIGTERM', toExit);
            process.on('exit', toExit);
        }
    };
}

export default {
    input: 'src/main.ts',
    output: {
        sourcemap: true,
        format: 'iife',
        name: 'app',
        file: 'public/build/bundle.js'
    },
    plugins: [
        svelte({
            preprocess: sveltePreprocess({ sourceMap: !production }),
            compilerOptions: {
                // enable run-time checks when not in production
                dev: !production
            }
        }),
        // we'll extract any component CSS out into
        // a separate file - better for performance
        css({ output: 'bundle.css' }),

        // If you have external dependencies installed from
        // npm, you'll most likely need these plugins. In
        // some cases you'll need additional configuration -
        // consult the documentation for details:
        // https://github.com/rollup/plugins/tree/master/packages/commonjs
        resolve({
            browser: true,
            dedupe: ['svelte']
        }),
        commonjs(),
        typescript({
            sourceMap: !production,
            inlineSources: !production
        }),

        // In dev mode, call `npm run start` once
        // the bundle has been generated
        !production && serve(),

        // Watch the `public` directory and refresh the
        // browser on changes when not in production
        !production && livereload('public'),

        // If we're building for production (npm run build
        // instead of npm run dev), minify
        production && terser()
    ],
    watch: {
        clearScreen: false
    }
};

这是我要导入的部分，这是swiper的官方svelte (https://swiperjs.com/svelte)文档中的代码：

<script>
    // import Swiper core and required modules
    import SwiperCore, { Navigation, Pagination, Scrollbar, A11y } from 'swiper';
    import { Swiper, SwiperSlide } from 'swiper/svelte';
    // Import Swiper styles
    import 'swiper/swiper.scss';
    import 'swiper/components/navigation/navigation.scss';
    import 'swiper/components/pagination/pagination.scss';
    import 'swiper/components/scrollbar/scrollbar.scss';
    // install Swiper modules
    SwiperCore.use([Navigation, Pagination, Scrollbar, A11y]);
</script>

请任何人回答这个问题。

嘿，我自己解决的，但如果有人需要帮助，我会在这里分享这一点。

因此，这是一种变通方法，而不是启用scss的完全可靠的解决方案。尽管scss已经在我的项目中，但不是只在swiper中工作。因此，解决方法是在swiper目录中有min.css文件。例如: swiper/swiper.scss有一个替代的swiper/swiper.bundle.min.css，所以你可以像这样改变一切：

// import Swiper core and required modules
    import SwiperCore, { Navigation, Pagination, Scrollbar, A11y } from 'swiper';
    import { Swiper, SwiperSlide } from 'swiper/svelte';
    // Import Swiper styles
    import 'swiper/swiper-bundle.min.css';
    import 'swiper/components/navigation/navigation.min.css';
    import 'swiper/components/pagination/pagination.min.css';
    import 'swiper/components/scrollbar/scrollbar.min.css';
    // install Swiper modules
    SwiperCore.use([Navigation, Pagination, Scrollbar, A11y]);
