我正在尝试实施ssr，但出现以下错误：

ERROR  Failed to compile with 1 error                                                                         16:11:16
This dependency was not found:
* module in ./node_modules/vue-server-renderer/build.dev.js
To install it, you can run: npm install --save module

在main.js文件中，我有以下代码：

const app = new Vue({
        i18n,
        router: routerInstance,
        render: h => h(App),
    }).$mount('#app')
    const renderer = require('vue-server-renderer').createRenderer({
        template: require('fs').readFileSync('./index.template.html', 'utf-8')
    })
    renderer.renderToString(app, (err, html) => {
        console.log(html) // will be the full page with app content injected.
    })

有什么想法吗？非常感谢。
