You can always setup the project manually.
Step 1 :
Install next, react and react-dom in your project:
npm install next react react-dom
Step 2 :
Open package.json and add the following scripts:
"scripts": {
"dev": "next dev",
"build": "next build",
"start": "next start"
}
Step 3: Populate ./pages/index.js with the following contents:
function HomePage() {
return <div>Welcome to Next.js!</div>
}
export default HomePage
To start developing your application run npm run dev or yarn dev. This starts the development server on http://localhost:3000.
UPDATE
Since you needed more help.
Create a new folder and name it as you like,then open your terminal & go into the project folder and run the step 1 commands. Now open package.json file and inside that write the step 2 code. Now create pages folder inside the current project directory and inside that create a index.js file and write the step 3 code. Now run the project by doing npm run dev.
So the project structure will be like this.
--Nextjs Project
---pages
|--- index.js
---packages.json
