Step 8 includes the command nvm install 10.22

If step 8 fails, you may need to check your ``/User/yourname/ folder for a file called .zshrc or .bash_profile` and then edit its contents.

• If you are running MacOS earlier than Catalina or Digital Ocean, use: .bash_profile
• If you are running MacOS Catalina or later, use: .zshrc

These files are hidden by default on MacOS. On Digital Ocean, you will need to use an FTP client to edit these files.

Open your main user directory and press Command + Shift + . (period) to show hidden files.

You will have either .zshrc or .bash_profile in that folder. Right-click it and use the “Open With” option to open this file with the application “Text Edit”

• If this file is blank, you need to add four lines of environment variables (copied and pasted below) and then save the file

  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
  

• Finally, type “exit” in your terminal window, quit out of the terminal, and then reopen your terminal window.
