在本指南中，我们将看看如何在RHEL / CentOS的和Fedora发行版安装最新版本的NodeJS和NPM的。
在Linux中安装Nodejs和NPM
是的NodeJS一个轻量级的，高效的JavaScript平台，基于Chrome的V8 JavaScript引擎构建和NPM是默认的NodeJS包管理器。 您可以使用它来构建可扩展的网络应用程序。
第1步：添加NodeSource Repository
的Node.js和NPM的最新版本可从官方NodeSource企业版Linux，Fedora 的 ，Debian和Ubuntu的二进制分发库，这是由网站的NodeJS维护和你需要将它添加到您的系统能够安装最新的和的NodeJS NPM包。
重要提示 ：在RHEL 5和CentOS 5，Node.js的包取决于EPEL软件库 ，因此该脚本将检查并下达指令，如果柜面它没有安装。
要添加存储库Node.js的V4 LTS氩的最新版本，请使用以下命令根..
在RHEL，CentOS和Fedora上
# curl --silent --location https://rpm.nodesource.com/setup_4.x | bash -
示例输出
## Installing the NodeSource Node.js 4.x LTS Argon repo... ## Inspecting system... + rpm -q --whatprovides redhat-release || rpm -q --whatprovides centos-release || rpm -q --whatprovides cloudlinux-release || rpm -q --whatprovides sl-release + uname -m ## Confirming "el7-x86_64" is supported... + curl -sLf -o /dev/null 'https://rpm.nodesource.com/pub_4.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm' ## Downloading release setup RPM... + mktemp + curl -sL -o '/tmp/tmp.PsUJCZaiu2' 'https://rpm.nodesource.com/pub_4.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm' ## Installing release setup RPM... + rpm -i --nosignature --force '/tmp/tmp.PsUJCZaiu2' ## Cleaning up... + rm -f '/tmp/tmp.PsUJCZaiu2' ## Checking for existing installations... + rpm -qa 'node|npm' | grep -v nodesource ## Run `yum install -y nodejs` (as root) to install Node.js 4.x LTS Argon and npm. ## You may also need development tools to build native addons: ## `yum install -y gcc-c++ make`
另外对Node.js的V6和Node.js的0.10添加以下信息库。
------- For Node.js v6 ------- # curl --silent --location https://rpm.nodesource.com/setup_6.x | bash - ------- For Node.js 0.10 ------- # curl --silent --location https://rpm.nodesource.com/setup | bash -
在Debian，Ubuntu和Linux Mint
$ sudo curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
示例输出

另外对Node.js的6版添加下面的资料库。
$ sudo curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
第2步：安装最新的Nodejs和NPM
接下来，你现在可以在系统上使用以下命令安装和的NodeJS NPM：
在RHEL，CentOS和Fedora上
# yum -y install nodejs npm # dnf -y install nodejs npm [On Fedora 23+ versions]
示例输出

可选 ：有开发工具，如gcc-C ++， 让您需要在您的系统上，为了从NPM构建本地插件。
------- On RHEL, CentOS and Fedora ------- # yum install gcc-c++ make ------- On Debian, Ubuntu and Linux Mint ------- $ sudo apt-get install -y build-essential
第3步：测试最新的Node.js和NPM
有和的NodeJS NPM的一个简单的测试，你可以通过检查使用以下命令在系统上安装的版本：
在RHEL，CentOS和Fedora上
# node --version # npm --version
CentOS 7 - 检查Nodejs和NPM版本
在Debian，Ubuntu和Linux Mint
$ nodejs --version $ npm --version
Ubuntu 15.10 - 检查Nodejs和NPM版本
这就是它，和的NodeJS NPM已经安装好了，您的系统上使用。
