📅  最后修改于: 2020-10-22 06:43:36             🧑  作者: Mango

由于Next.js是基于反应的框架，因此我们正在使用Node环境。现在，请确保您已在系统上安装了Node.js和npm 。您可以使用以下命令安装Next.js-

npm install next react react-dom

成功安装Next.js后，您可以观察到以下输出-

+ react@16.13.1
+ react-dom@16.13.1
+ next@9.4.4
added 831 packages from 323 contributors and audited 834 packages in 172.989s

现在，让我们创建一个节点package.json-

npm init

创建package.json时选择默认值-

This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help json` for definitive documentation on these fields
and exactly what they do.

Use `npm install ` afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.
package name: (nextjs)
version: (1.0.0)

test command:

About to write to \Node\nextjs\package.json:
{
   "name": "nextjs",
   "version": "1.0.0",
   "description": "",
   "main": "index.js",
   "dependencies": {
      "next": "^9.4.4",
      "react": "^16.13.1",
      "react-dom": "^16.13.1"
   },
   "devDependencies": {},
   "scripts": {
      "test": "echo \"Error: no test specified\" && exit 1"
   },
   "author": "",
   "license": "ISC"
}
Is this OK? (yes)

现在更新package.json的脚本部分，以包含Next.js命令。

{
   "name": "nextjs",
   "version": "1.0.0",
   "description": "",
   "main": "index.js",
   "dependencies": {
      "next": "^9.4.4",
      "react": "^16.13.1",
      "react-dom": "^16.13.1"
   },
   "devDependencies": {},
   "scripts": {
      "test": "echo \"Error: no test specified\" && exit 1",
      "dev": "next",
      "build": "next build",
      "start": "next start"
   },
   "author": "",
   "license": "ISC"
}

创建页面目录。

在nextjs文件夹中创建一个pages文件夹，并创建一个包含以下内容的index.js文件。

function HomePage() {
   return 
Welcome to Next.js!

}

export default HomePage

启动Next.js服务器

运行以下命令以启动服务器-。

npm run dev
> nextjs@1.0.0 dev \Node\nextjs
> next

ready - started server on http://localhost:3000
event - compiled successfully
event - build page: /
wait  - compiling...
event - compiled successfully
event - build page: /next/dist/pages/_error
wait  - compiling...
event - compiled successfully

验证输出

在浏览器中打开localhost：3000，您将看到以下输出。
