javascript - 汇总未生成 typescript 源图

Question

我正在使用带有 svelte + typescript + scss 的汇总。我的问题是我无法生成源 map 。
以下是我的汇总配置文件:

import svelte from 'rollup-plugin-svelte'
import resolve from '@rollup/plugin-node-resolve'
import commonjs from '@rollup/plugin-commonjs'
import livereload from 'rollup-plugin-livereload'
import { terser } from 'rollup-plugin-terser'
import typescript from '@rollup/plugin-typescript'
import alias from '@rollup/plugin-alias'
    
const production = !process.env.ROLLUP_WATCH
const path = require('path').resolve(__dirname, 'src')
const svelteOptions = require('./svelte.config')
    
function serve() {
    let server
    
    function toExit() {
        if (server) server.kill(0)
    }
    
    return {
        writeBundle() {
            if (server) return
            server = require('child_process').spawn(
                'yarn',
                ['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: [
        alias({
            entries: [
                { find: '@app', replacement: `${path}` },
                { find: '@components', replacement: `${path}/components` },
                { find: '@includes', replacement: `${path}/includes` },
                { find: '@styles', replacement: `${path}/styles` },
                { find: '@pages', replacement: `${path}/pages` },
            ],
        }),
        svelte(svelteOptions),
    
        // 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 }),
    
        // 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,
    },
}

我不确定我到底做错了什么。这里是 link我正在使用的代码。
任何帮助将不胜感激!

这对我有用:您需要设置 sourceMap: false在 typescript汇总插件选项。

export default {
  input: 'src/main.ts',
  output: {
    sourcemap: true,
    format: 'iife',
    ...
  },
  plugins: [
    ...
    svelte(...),
    typescript({ sourceMap: false }),
    ...
  ]
}

事实证明，汇总的源映射折叠器与 typescript 的插件源映射生成器冲突。这就是为什么它适用于 prod 构建但不适用于 dev 构建(因为最初它是 sourceMap: !production )。只需让 rollup 完成繁重的工作。
