Need help with git issue

I’m doing a tutorial on utilizing ChatGPT and I’m trying to import a git package using a git URL. However every time I click add after pasting the URL in I get the following error "
[Package Manager Window] Error adding package: GitHub - srcnalt/OpenAI-Unity: An unofficial OpenAI Unity Package that aims to help you use OpenAI API directly in Unity Game engine..
Unable to add package [GitHub - srcnalt/OpenAI-Unity: An unofficial OpenAI Unity Package that aims to help you use OpenAI API directly in Unity Game engine.]:
No ‘git’ executable was found. Please install Git on your system then restart Unity and Unity Hub
UnityEditor.EditorApplication:Internal_CallUpdateFunctions ()"

I’ve tried everything I can think of and I keep getting this error, what should I do?

It’s quite funny that you want to use OpenAI in the project and don’t ask OpenAI for a solution.

Please only post things related to 2D on the 2D forum.

I’ll move this post.
