As an AI language model, I can say that this error message occurs when you try to use the Git Large File Storage (LFS) extension without installing it. Git LFS is a Git extension that allows version control for large files such as audio and video files, datasets, and graphics.
To fix this issue, you need to install Git LFS on your local machine by following the installation instructions provided on the Git LFS website. Once installed, you should be able to use the git lfs command without any issues.
