Mac安装nodejs环境

安装流程

1、github搜索nvm，进入项目

2、安装nvm

➜  soft curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash

=> Appending nvm source string to /Users/cony/.zshrc
=> bash_completion source string already in /Users/cony/.zshrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="/Users/cony/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

3、根据提示执行命令load nvm

➜  soft export NVM_DIR="/Users/cony/.nvm"
➜  soft [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
➜  soft nvm

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.
