Element UI - Unknown custom element: <el-drawer> - did you register the component correctly?

I am using the element ui template, but when adding some components such as el-drawer, it appears to me that it is not registered,

https://element.eleme.io/#/es/component/drawer

vue.runtime.esm.js:574 [Vue warn]: Unknown custom element: <el-drawer> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

         <Layout> at src/layout/index.vue
           <App> at src/App.vue
How can I add or fix it?
Thank you
