简介：
nvm：nodejs 版本管理工具，一个nvm可以管理很多node版本和npm版本
nodejs：在项目开发时的所需要的代码库
npm：nodejs 包管理工具nvm、nodejs、npm的关系：
nvm 管理 nodejs 和 npm 的版本。npm 可以管理 nodejs 的第三方插件。
安装 nvm
可以使用curl
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash或者使用wget
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash都可以的，到这步一般情况下都没问题，然后终端输入 nvm，然后看到如下打印信息就可以了
Node Version Manager
Note: <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.
Usage:
nvm --help Show this message
nvm --version Print out the installed version of nvm
nvm install [-s] <version> Download and install a <version>, [-s] from source. Uses .nvmrc if available
--reinstall-packages-from=<version> When installing, reinstall packages installed in <node|iojs|node version number>
--lts When installing, only select from LTS (long-term support) versions
--lts=<LTS name> When installing, only select from versions for a specific LTS line
--skip-default-packages When installing, skip the default-packages file if it exists
--latest-npm After installing, attempt to upgrade to the latest working npm on the given node version
--no-progress Disable the progress bar on any downloads
nvm uninstall <version> Uninstall a version
nvm uninstall --lts Uninstall using automatic LTS (long-term support) alias `lts/*`, if available.

--lts When listing, only show LTS (long-term support) versions
--lts=<LTS name> When listing, only show versions for a specific LTS line
nvm version <version> Resolve the given description to a single local version
nvm version-remote <version> Resolve the given description to a single remote version

nvm alias default 8.1.0 Set default node version on a shell
nvm alias default node Always default to the latest available node version on a shell
Note:
to remove, delete, or uninstall nvm - just remove the `$NVM_DIR` folder (usually `~/.nvm`)如果呢，你没有看到，而是出现 command not found: nvm 你可以排查下是否有.bash_profile 这个文件，别人都是这么说的，你可以排查下，没有这个文件就建一个，然后把如下加入到环境变量里保存，然后source ~/.bashrc这个命令生效，就可以了，更多请详见nvm
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvmnvm 常用命令
nvm install stable ## 安装最新稳定版 node，当前是node v9.5.0 (npm v5.6.0)
nvm install <version> ## 安装指定版本，可模糊安装，如：安装v4.4.0，既可nvm install v4.4.0，又可nvm install 4.4
nvm uninstall <version> ## 删除已安装的指定版本，语法与install类似
nvm use <version> ## 切换使用指定的版本node
nvm ls ## 列出所有安装的版本
nvm ls-remote ## 列出所有远程服务器的版本（官方node version list）
nvm current ## 显示当前的版本
nvm alias <name> <version> ## 给不同的版本号添加别名
nvm unalias <name> ## 删除已定义的别名
nvm reinstall-packages <version> ## 在当前版本 node 环境下，重新全局安装指定版本号的 npm 包本文章是转载...
