Atom won't let me add a github repository

I am new to atom, and as soon as I installed it, I wanted to start coding! So I clicked “Clone an existing GitHub repository”. It asked me to “Clone from” and I pasted the link of my GitHub repository. I pasted: “https://github.com/theknightD2/scorekeepr.git”. This is the error I got: Cloning into ‘/Users/home/github/scorekeepr’… fatal: unable to find remote helper for ‘https’. I have atom nightly. If anyone could help, I would appreciate it greatly!
