直接安装nvm报错，按照提示先新建文件夹.nvm，再修改环境变量

Please note that upstream has asked us to make explicit managing
nvm via Homebrew is unsupported by them and you should check any
problems against the standard nvm install method prior to reporting.
You should create NVM's working directory if it doesn't exist:
  mkdir ~/.nvm
Add the following to your shell profile e.g. ~/.profile or ~/.zshrc:
  export NVM_DIR="$HOME/.nvm"
  [ -s "/home/linuxbrew/.linuxbrew/opt/nvm/nvm.sh" ] && \. "/home/linuxbrew/.linuxbrew/opt/nvm/nvm.sh"  # This loads nvm
  [ -s "/home/linuxbrew/.linuxbrew/opt/nvm/etc/bash_completion.d/nvm" ] && \. "/home/linuxbrew/.linuxbrew/opt/nvm/etc/bash_completion.d/nvm"  # This loads nvm bash_completion

$ nvm -v
