Step 6 includes a command that starts with curl -o-

First check the NVM install page to make sure you are using the most recent version.

Then, look for what programmers call a pipe, the vertical line after “install.sh” that looks like this: | . Pipes separate the main part of a command in the command line from an extension of that command that might have some variances from system to system. Adjust what comes after it based on your MacOS.

• If you are running MacOS earlier than Catalina or Digital Ocean, use:
  • curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
• If you are running MacOS Catalina or later, use:
  • curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | zsh
• Remember that spaces also act as separators in the command line. You’ll need a space before and after the pipe.
