nodejs安装（linux）-npm 命令-工具盒子

npm 命令

npm i node-sass --sass_binary_site=https://npm.taobao.org/mirrors/node-sass/

npm install --registry=https://registry.npm.taobao.org

npm run build

查看版本：

node -v 
npm -v

nodejs 设置仓库（缓存-镜像加速）: 连接

1-查看当前使用的仓库

npm config get registry

成功安装：

1- 下载

https://nodejs.org/en/download

各个版本下载：https://nodejs.org/dist/

v16.20.2 针对 centos 7.9 是不需要依赖的。

18.19,20 需要安装 glibc_ , node v18开始都需要GLIBC_2.27支持

解决方法： node: /lib64/libm.so.6: version `GLIBC_2.27' not found - 丁少华 - 博客园 (cnblogs.com)

我这里下载的是 v20.10.0

https://nodejs.org/dist/v20.10.0/

wget https://nodejs.org/dist/v20.10.0/node-v20.10.0-linux-x64.tar.gz

2-安装

解压：

 tar xf node-v20.10.0-linux-x64.tar.gz

3-配置环境变量

vim /etc/profile

export PATH=$PATH:/opt/node-v20.10.0-linux-x64/bin

source /etc/profile

1-安装Node.js 16

v18.18.2

Node.js 包是通过 NodeSource Node.js Binary Distributions 和 .rpm 提供的。使用以下命令将存储库添加到系统：

curl -fsSL https://rpm.nodesource.com/setup_16.x | sudo bash -

2-安装nodejs

yum install -y nodejs

3-验证

node

退出

.exit

4-安装构建时会用到的原生插件：

yum install -y gcc-c++ make

5-安装 pm2

PM2是JavaScript运行时Node.js的进程管理器。

npm install -g pm2

如果比较慢，可以设置镜像加速,参考文章开头。

6-Yarn 包管理器

curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
 yum install -y yarn

直接上demo.js：

//得到内置模块，引入NodeJS的内置 http 模块 
var http = require('http');
// 创建服务器，使用createServer方法
var server = http.createServer(function(req,res){
  // req：请求，res: 响应
  // 返回 / 输出
  res.setHeader("Content-Type","text/html;charset=UTF8");
  res.end("hello NodeJs 呀");

});
// port:3000
server.listen(3000);

运行：

 pm2 start demo.js
