Install vue and import Element UI

First, enter in the terminal of the Vue project: npm i element-ui -S (after entering, press Enter, wait for a while, and the content below the red box in the figure below will appear, indicating that the installation has been successful)

Then, add in main.js:

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

Vue.use(ElementUI);

After completing the above steps, you can check whether it is installed: you can see the relevant information of Element UI in package.json

 Finally, you can test it. The following is the case on the official document:
