I found an error when npm start to launch starter project  
_[vite] Internal server error: Failed to resolve import “react-router” from “src/pages/admin/AdminLayout.tsx”. Does the file exist?_

go to src/pages/admin/AdminLayout.tsx  
replace  
`import { Outlet } from "react-router";`  
by :  
`import { Outlet } from "react-router-dom";`
