一、安裝 nvm--node版本管理工具
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
在配置文件（~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc）末尾添加下列內(nèi)容：
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
刷新配置：
bash: source ~/.bashrc
zsh: source ~/.zshrc
ksh: . ~/.profile
用法：
nvm install node # "node" is an alias for the latest version
nvm install 6.14.4 # or 10.10.0, 8.9.1, etc
nvm ls-remote # list available versions
nvm use node # use the installed version
nvm run node --version # run
nvm which 5.0 # get the path to the executable to where it was installed
安裝后泳唠，通過nvm ls查看：
nvm ls
二幸逆、 安裝nrm -- NPM registry manager
npm install -g nrm
安裝完成后執(zhí)行 nrm ls:
* npm ------- https://registry.npmjs.org/
yarn ------ https://registry.yarnpkg.com
tencent --- https://mirrors.cloud.tencent.com/npm/
cnpm ------ http://r.cnpmjs.org/
