【vuepress2中打包报错】SyntaxError: Named export 'createI18n' not found. The requested module 'vue-i18n/dist/vue-i18n.runtime.esm-bundler.js' is a CommonJS module, which may not support all module.exports as named exports.

Reporting a bug?

import { createI18n, useI18n } from "vue-i18n/dist/vue-i18n.runtime.esm-bundler.js";
         ^^^^^^^^^^
SyntaxError: Named export 'createI18n' not found. The requested module 'vue-i18n/dist/vue-i18n.runtime.esm-bundler.js' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'vue-i18n/dist/vue-i18n.runtime.esm-bundler.js';
const { createI18n, useI18n } = pkg;

    at ModuleJob._instantiate (node:internal/modules/esm/module_job:124:21)
    at async ModuleJob.run (node:internal/modules/esm/module_job:190:5)
 ELIFECYCLE  Command failed with exit code 1.

Expected behavior

运行命令：pnpm docs:bulid 就会报错，如果时正常运行是可以使用的！

添加 noExternal 后可以打包

bundler: viteBundler({
    viteOptions: {
      plugins: [

        svgLoader(),
        // https://github.com/intlify/bundle-tools/tree/main/packages/vite-plugin-vue-i18n
        VueI18nPlugin({
          runtimeOnly: true,
          compositionOnly: true,
          include: [resolve(__dirname, "../../locales/**")],
        }),
      ],
      ssr: {
        /**

        noExternal: ['vue-i18n']
      }
    }
  }),

This issue is around cjs / esm in bundler, it can be worked around in bundler configuration. vue-i18n is esm first. vue-i18n is esm first and also provides cjs. You can check in the vue-i18n dist directory.

Thanks!
