Vue项目用vite-plugin-md遇ERR_PACKAGE_PATH_NOT_EXPORTED错误求助

问题详情 #

我在构建Vue应用时，尝试使用vite-plugin-md作为Markdown加载器，完全按照其官方文档配置了vite.config.js：

/* vite.config.js */

import { fileURLToPath, URL } from 'node:url'

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { Markdown } from 'vite-plugin-md'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue({
      include: [/\.vue$/, /\.md$/], // <--
    }),
    Markdown(),
  ],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url))
    }
  }
})

但执行npm run dev时出现如下错误：

failed to load config from /route/md-demo/vite.config.js
error when starting dev server:
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in /route/md-demo/node_modules/@yankeeinlondon/happy-wrapper/package.json

    at Object.<anonymous> (/route/md-demo/node_modules/vite-plugin-md/dist/index.cjs:18031:28)

我已经尝试通过错误关键词搜索相关帖子，并执行了npm update，但问题仍未解决。

解决方案 #

在项目根目录的package.json中添加"type": "module"字段即可解决该问题，此方案来自vite-plugin-md官方讨论。
