Module is a CommonJS module, which may not support all module.exports as named exports.
Reporting a bug?
Hello! I'm using vite-ssr-plugin with vue3 and i18n with unplugin-vue-i18n On build mode I have an error. But on dev mode everything is great.
import { useI18n, createI18n } 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 { useI18n, createI18n } = pkg;
Found this comment about this problem, https://github.com/intlify/vue-i18n-next/issues/1131#issuecomment-1232596381
And explanation https://github.com/vuejs/core/pull/4814#issuecomment-1232806856
Also there are solution for vite-plugin-vue-i18n https://github.com/intlify/bundle-tools/pull/172
But I can't find solutions for unplugin-vue-i18n
Also opened issue in repo vite-plugin-ssr https://github.com/brillout/vite-plugin-ssr/issues/634
If change ssr parameter in vite.config.ts - building is successfull.
According to the documentation ssr can be customized with 4 keys. I'm trying to find out wich key is causing build error.
Expected behavior
No error on build mode

Additional context
In vite.config.ts config file
import vue from '@vitejs/plugin-vue';
import ssr from 'vite-plugin-ssr/plugin';
import VueI18nPlugin from '@intlify/unplugin-vue-i18n/vite';
const config: UserConfig = {
plugins: [
vue(),
ssr({ prerender: true, includeAssetsImportedByServer: true }),// If put here ssr(), without parametrs - building successfull, without errors
VueI18nPlugin({
include: resolve(dirname(fileURLToPath(import.meta.url)), './locales/dictionary/**'),
}),
],
resolve: {
alias: {
'vue-i18n': 'vue-i18n/dist/vue-i18n.runtime.esm-bundler.js',
},
},
};
createI18n used in app.ts with this:
import messages from '@intlify/unplugin-vue-i18n/messages';
export { createApp };
function createApp(pageContext: PageContext) {
const { Page, pageProps } = pageContext;
const i18n = createI18n({
legacy: false,
locale: pageContext.locale,
fallbackLocale: 'en',
messages,
});
const PageWithLayout = defineComponent({
render() {
return h(
PageShell,
{},
{
default() {
return h(Page, pageProps || {});
},
}
);
},
});
const app = createSSRApp(PageWithLayout);
app.use(i18n);
app.use(vuetify);
app.use(CountryFlag);
app.provide('pageContext', pageContext);
setPageContext(app, pageContext);
return app;

The same error with @intlify/unplugin-vue-i18n 0.8.2

我也遇见类似的问题，我是在项目中集成了vuepress2，想在vuepress展示自己开发的组件。结果导致无法执行pnpm docs:build。异常信息如下：
import { createI18n, useI18n } from "vue-i18n/dist/vue-i18n.runtime.esm-bundler.js";

Well, for solve this error i removed i18n from project, and tried to use self-written package for internationalization.
@alivadjid, The issue is with the Vite plugin unplugin-vue-i18n, not vue-i18n. The unplugin-vue-i18n plugin is optional for vue-i18n. You can import messages yourself, as described in the documentation.
However, it is very sad that the declared functionality of this plugin does not work.
@alivadjid 我也有类似的问题，我找到了一个折衷方案，希望能够帮助到您，下方是我的的配置：（I have similar problems. I have found a compromise that I hope will help you. Below is my configuration:）
ssr: {
/**
* 由于在 build 时会报错 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.
* 所以要添加以下配置。详见：https://vite-plugin-ssr.com/common-issues 与 https://vite-plugin-ssr.com/invalid-esm#solution

@WangJincheng4869 Your solution fixed my production build but then I could not start my App in dev mode anymore ("module not found"). I uninstalled unplugin-vue-i18n and used vue-i18n directly and now it works in dev and prod.
@WangJincheng4869 Your solution fixed my production build but then I could not start my App in dev mode anymore ("module not found"). I uninstalled unplugin-vue-i18n and used vue-i18n directly and now it works in dev and prod. use const isProduction = process.env.NODE_ENV === 'production';
to do some special case in vite config file.
