如果我在MacBook Pro上重新打开终端，则找不到nvm

Question

I ran the following commands to install NVM:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.5/install.sh | bash

export NVM_DIR="$HOME/.nvm"
[ -s "$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 

It works fine and I can run nvm without any issue but once I close and re-open the terminal it prompts with the following error:

-bash: nvm: command not found

What is wrong?

MAC Version: 10.14.5

I have already node v11.13.0 installed.

如https://github.com/nvm-sh/nvm所述，在安装nvm之前，我必须先运行touch〜 touch ~/.bash_profile 。
