You can do two things:
1. Use your command prompt, You need to have node and npm latest stable versions installed. Navigate into your folder directory where your project is and run npm i grapesjs wait for a while and then a package.json file should be created check it to see if grapesjs is there then require it in wherever you want to use it.

Link both the css and js files in your index file or where you want to use it. Then go to their documentation site https://github.com/artf/grapesjs/wiki try out an example to see if everything checks out fine
