symfony管理员捆绑安装

Question

I am learning the symfony sonata bundle, I installed the symfony skeleton project with composer create-project symfony/website-skeleton sonata command, and I enter into sonata directory and run composer require sonata-project/admin-bundle command as the guide on symfonydoc , I checked all the configurations as the doc said, and the cache:clear and assets:install command all work fine, I started my server with php bin/console server:start , but when I visit the url ' http://localhost:8000/admin/dashboard ' it reports error, An exception has been thrown during the rendering of a template ("Asset manifest file "/Users/kazuma/www/sonata/public/build/manifest.json" does not exist.").

I made my project with symfony before, but I don't know much about the webpack, my asset directory is empty, when I run npm install it works fine too, I don't know what I've missed.
