I’m extremely new to development. I’m trying to install a Ghost instance (apologies if this is not the correct terminology; feel free to correct). I created a directory on my desktop called “Ghost” and inside that, following Ghost’s (ghost-cli 1.24.0) instructions, I typed out `ghost install local` in that directory in the terminal.

What follows is a series of inscrutable errors.

Here is that:

I’m not even sure what to try, but I’ve tried: I’ve updated the latest supported version of node, NPM, and yarn. I’ve reverted to an earlier, but supported version of node 16.13.0.

Here’s the actual error, it looks like you either don’t have Python installed, or it’s not able to be found

Thank you!

I don’t have python on my computer. I looked up how to install and it suggested homebrew. I installed homebrew (which installed Xcode Command Line Tools) and tried the Ghost install again and it worked! But, apparently, I _still_ don’t have python on my computer.

So, I guess this is the solve?

The same error was made on my Mac, too. I uninstall Node v18 and install Node v14. It rectified the error.
