git-lfs: command not found
I’m getting an error when I try to commit, it’s something to do with `git-lfs` but I don’t fully understand what it means.
- I ran the `git lfs install && git lfs track '*.png' && git lfs track '*.sketch' && git add .gitattributes` at the before trying to commit anything. 
- I made some changes to the names of my **Artboards**
- I saved
- I committed using the Git plugin UI
- I then got this message:

`git-lfs clean '.exportedArtboards/Jellyfish/1-Dashboard.png': git-lfs: command not found
error: external filter git-lfs clean 0.000000 failed -1
error: external filter git-lfs clean 0.000000 failed
fatal: .exportedArtboards/Jellyfish/1-Dashboard.png: clean filter 'lfs' failed`

Any idea what’s causing the error? I don’t understand why it says `git-lfs: command not found` when I got the `Git LFS initialized.` message after running the `git lfs install` command.
