For the sole purpose to use SASS, you need to install Ruby the right way. That is with either RBENV or RVM. If you are not going to do the Ruby on Rails training, I highly encorage you to do it with RVM.
Run the following commands in your terminal:
git branch -m old_branch new_branch # Rename branch locally | |
git push origin :old_branch # Delete the old branch | |
git push --set-upstream origin new_branch # Push the new branch, set local branch to track the new remote |
