web開發環境搭建 一、安裝 nvm--node版本管理工具 二、 安裝nrm -- NPM registry manager 三、進入項目目錄，安裝依賴

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

安裝後，通過nvm ls查看：

二、 安裝nrm -- NPM registry manager

npm install -g nrm 

安裝完成後執行 nrm ls:

* npm ------- https://registry.npmjs.org/
  yarn ------ https://registry.yarnpkg.com
  tencent --- https://mirrors.cloud.tencent.com/npm/
  cnpm ------ http://r.cnpmjs.org/
  taobao ---- https://registry.npm.taobao.org/
  nj -------- https://registry.nodejitsu.com/
  skimdb ---- https://skimdb.npmjs.com/registry

Usage: nrm [options] [command]

  Commands:

    ls                                    List all the registries
    current                               Show current registry name
