Teammates code (python) won't run on atom, even though mine does

So we have downloaded Atom-Runner,Script,Teletype packages in order to collaborate with each other on a project. Since i’m the host of the portal and invited partners through a link to join in the development of my project, whenever I attempt to run my python script in Atom, it works.

Unfortunately, whenever my friend tries to run it, an error saying this pops up:

"python: can’t open file ‘@jlhuangai:untitled’: [Errno 2] No such file or directory "

It was quite frustruating as we were only able to edit our code on atom, but my other partners were not able to run the script/code on directly itself.

Thanks in advance!
