The npm packages for the _mandatory_ polyfills (such as `zone.js`) were installed automatically for you when you created your project and their corresponding `import` statements are ready to go. You probably won't touch these.

**强制性** 填充脚本（如`zone.js`）的npm 包在创建工程时就已经自动安装了，相应的 `import` 语句也都加好了。我们一般不用动它们。
