1 NVM简介
-
nvm是什么
nvm是nodejs 的版本管理器，旨在按用户要求进行安装并按进行shell调用。nvm适用于任何符合POSIX的shell（sh、dash、ksh、zsh、bash），特别是在以下平台上：
- unix
- macOS
- windows WSL
2 NVM安装
可以通过如下的cURL或者wget命令之一进行安装:
- cURL
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
- wget
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
安装之后，为了是nvm命令能够被识别和生效，可以重启terminal或者执行屏幕提示的脚本：
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 nvm
查看可用的nvm命令:
$ nvm -h
Node Version Manager (v0.38.0)
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
--no-colors Suppress colored output
nvm --version Print out the installed version of nvm
nvm install [<version>] Download and install a <version>. Uses .nvmrc if available and version is omitted.
