ubuntu下使用nvm安装各种版本的node

git clone nvm

直接从 github clone nvm 到本地, 这里假设大家都使用 ~/git 目录存放 git 项目:

$ cd ~/git
$ git clone https://github.com/creationix/nvm.git

配置终端启动时自动执行 source ~/git/nvm/nvm.sh,在 ~/.bashrc, ~/.bash_profile, ~/.profile, 或者 ~/.zshrc 文件添加以下命令:

source ~/git/nvm/nvm.sh

重新打开你的终端, 输入 nvm

twitch@laravel:~$ nvm

Node Version Manager

Note:  refers to any version-like string nvm understands. This includes:
  - full or partial version numbers, starting with an optional "v" (0.10, v0.1.2, v1)
  - default (built-in) aliases: node, stable, unstable, iojs, system
  - custom aliases you define with `nvm alias foo`

 Any options that produce colorized output should respect the `--no-colors` option.

Usage:
  nvm --help                                Show this message

通过 nvm 安装任意版本的 node
nvm 默认是从 http://nodejs.org/dist/ 下载的,国外服务器, 必然很慢,好在 nvm 以及支持从镜像服务器下载包, 于是我们可以方便地从七牛的 node dist 镜像下载:

$ NVM_NODEJS_ORG_MIRROR=https://npm.taobao.org/mirrors/node nvm install 4

于是你就会看到一段非常快速进度条:
######################################################################## 100.0%Now using node v4.6.1

如果你不想每次都输入环境变量 NVM_NODEJS_ORG_MIRROR, 那么我建议你加入到 .bashrc 文件中:

# nvm
export NVM_NODEJS_ORG_MIRROR=https://npm.taobao.org/mirrors/nodesource ~/git/nvm/nvm.sh

然后你可以继续非常方便地安装各个版本的 node 了, 你可以查看一下你当前已经安装的版本:

twitch@laravel:~$ nvm ls
 ->       v4.6.1
default -> 4 (-> v4.6.1)
node -> stable (-> v4.6.1) (default)
stable -> 4.6 (-> v4.6.1) (default)
iojs -> N/A (default)
lts/* -> lts/boron (-> N/A)
lts/argon -> v4.6.1
lts/boron -> v6.9.1 (-> N/A)

通过 nvm 安装任意版本的 node

nvm 默认是从 http://nodejs.org/dist/ 下载的,国外服务器, 必然很慢,npm也是从国外服务器下载的,基本下载不下来好在 nvm 以及支持从镜像服务器下载包, 于是我们可以方便地从淘宝的 node dist 镜像下载:

set "NVMW_NODEJS_ORG_MIRROR=https://npm.taobao.org/mirrors/node"set "NVMW_NPMJS_COM_MIRROR=https://npm.taobao.org/mirrors/npm"nvm install 4.3.2
