How to install nvm in Mac (detailed tutorial)

The following editor will share with you a tutorial on installing nvm on Mac. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor to take a look

1. Install nvm

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash
安装成功默认将会在用户文件夹中生成一个隐藏的 .nvm 文件
显示隐藏文件：defaults write com.apple.finder AppleShowAllFiles Yes && killall Finder
隐藏隐藏文件：defaults write com.apple.finder AppleShowAllFiles No && killall Finder

2. View the configuration file .bash_profile

If there is no configuration file, you can copy and paste a hidden file in .nvm to change the name and change the content to the following code: (Note: The user name pointed to by NVM_DIR can be searched in spotlight" User folder", check it)

export NVM_DIR="/Users/你的用户名/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion

3. Make the configuration file .bash_profile effective (otherwise it will report: nvm: command not found)

source ~/.nvm/.bash_profile

4. Common nvm commands

The following uses version 8.9.2 as an example

nvm ls ：打印出所有的版本
nvm install stable：安装最稳定的版本
nvm install v8.9.2 ： 安装node的8.9.2的版本（删除用uninstall）
nvm current ：当前使用的node版本
nvm use v8.9.2 ：将node改为8.9.2版本
nvm alias default 0.12.7：设置默认 node 版本为 0.12.7
nvm alias default ：设置系统默认的node版本
nvm alias ：给不同的版本号添加别名
nvm unalias ： 删除已定义的别名
nvm reinstall-packages ：在当前版本node环境下，重新全局安装指定版本号的npm包
npm install -g mz-fis：安装 mz-fis 模块至全局目录，安装的路径：/Users/<你的用户名>/.nvm/versions/node/v0.12.7/lib/mz-fis
nvm use 4：切换至 4.2.2 版本（支持模糊查询）
npm install -g react-native-cli：安装 react-native-cli 模块至全局目录，安装的路径：/Users/<你的用户名>/.nvm/versions/node/v4.2.2/lib/react-native-cli

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
