You should create NVM's working directory if it doesn't exist:

  mkdir ~/.nvm

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

  export NVM_DIR="$HOME/.nvm"
  [ -s "/usr/local/opt/nvm/nvm.sh" ] && . "/usr/local/opt/nvm/nvm.sh"  # This loads nvm
  [ -s "/usr/local/opt/nvm/etc/bash_completion.d/nvm" ] && . "/usr/local/opt/nvm/etc/bash_completion.d/nvm"  # This loads nvm bash_completion

You can set $NVM_DIR to any location, but leaving it unchanged from
/usr/local/opt/nvm will destroy any nvm-installed Node installations
upon upgrade/reinstall.

Type `nvm help` for further information.

Bash completion has been installed to:
  /usr/local/etc/bash_completion.d

pytest的setup和teardown是利用@pytest.fixture这个注释来完成的.不仅可以完成初始化操作,初始化后如果有数据需要给用例使用也是非常方便!
