组件库用npm init @alilc/element新建项目后，安装成功，启动时一直没动静，也没报错

## **To Reproduce (required)** / **如何复现 bug？（必填，非常重要）**

npm init @alilc/element xxx
cd xxx
npm install
npm run lowcode:dev
打开localhost:3333 一直loading
发现请求https://dev.g.alicdn.com/ali-lowcode/ali-lowcode-engine/0.16.6/engine-core.js和https://dev.g.alicdn.com/ali-lowcode/ali-lowcode-engine/0.16.6/engine-core.css失败

## **Expected behavior (required)** / **预期行为（必填，非常重要）**
可以打开localhost:3333

Start by running `npm init @alilc/element xxx`, `npm install`, and `npm run lowcode:dev`, then inspect the generated project's startup entry and the failed requests from localhost:3333. Check why the ali-lowcode-engine 0.16.6 engine-core.js and engine-core.css URLs fail; done means the local page loads successfully.
