第2章 安装Nodejs 2-4 Linux下安装Nodejs

linux下编译安装Nodejs

 GCC和G++分别是GNU的C和C++编译器。它们在执行编译工作的时候把源代码通过预处理转化成汇编语言生成.i后缀的文件，再由汇编变成目标机器代码，最后连接目标代码生成可执行程序。就可以在命令行里面通过系统路径来直接调用了。

所以呢要安装Nodejs首先就要先扫平这些环境问题。比Windows上傻瓜式的安装要复杂一些。

我演示用的服务器是托管在登记在DigitalOcean身上的CentOS。其他的linux系统安装也大同小异。

首先我需要查看当前系统的发行版本。CentOS是通过Red Hat社区发布的。

Nodejs源码主要是通过C++代码和JavaScript代码构成的。但是它是通过gyp这个跨平台构建工具管理你的项目源码。gyp是用Python语言写的，因此在安装Nodejs的时候是需要Python 2.6或者是2.7的版本。但是官方并不推荐使用3.0的版本。

有时候你安装失败往往是由于Python的版本太旧或者它在系统中的安装路径不对。

https://github.com/nodejs/node

在Nodejs的项目根目录下就能看到一个Makefile文件。

到Nodejs的官网复制一下源码的链接，我们要用源码编译的方式来安装。
