Make versions of node interchangeable to fit different business

Uninstall node if you used pkg to install before

1	`sudo rm -rf /usr/local/{bin/{node,npm},lib/node_modules/npm,lib/node,share/man//node.}`

Then install nvm through brew

1	`brew install nvm`

Set local path to ~/.zshrc then resource it

Add the following to ~/.zshrc or your desired shell
configuration file:

  export NVM_DIR="$HOME/.nvm"
  [ -s "/opt/homebrew/opt/nvm/nvm.sh" ] && \. "/opt/homebrew/opt/nvm/nvm.sh"  # This loads nvm
  [ -s "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" ] && \. "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm"  # This loads nvm bash_completion
source ~/.zshrc

check  version of nvm
nvm -v

Begin to install node

Check available version we can use at present

1	`nvm list available`

Install appointed version if you like ,here we recommend to install v12.20.1 or whatever you prefer

nvm install 12.20.1

nvm use --delete-prefix v12.20.1

nvm use 12.20.1

# set default version
nvm alias default 12.20.1

# check if node is successfully installed

node -v

npm -v

Sometimes it is necessary to restart system to make it into effect~Just drink a java to wait.

有时候抽风需要重启一下~~~~

重装node，用nvm 来管理node版本
