NVM（node version manager）是一个可以让你在同一台机器上安装和切换不同版本 node 的工具。
如果系统没有安装 git 的话，需先安装 git。
在终端输入以下命令安装 NVM。
# 安装 NVM
$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash安装完成后在终端中输入以下命令配置环境变量。
# 打开环境变量配置文件
$ vim ~/.bash_profile在 .bash_profile 文件中添加一下字段。
source ~/.bashrc保存文件退出，在终端中输入以下命令使配置生效。
# 使环境变量配置生效
$ source ~/.bash_profile常用命令
# 查看该系统已经安装的版本，这个命令也能看到当前使用的是哪个版本
$ nvm ls
# 列出全部可以安装的版本号
$ nvm ls-remote
# 安装指定版本
$ nvm install [version]
$ nvm install v10.2.0
# 切换到指定版本，切换效果是全局的
$ nvm use [version]
$ nvm use v10.2.0
# 查看当前使用的版本
$ nvm currentNote: <version> 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.
