Question

I am getting an error when trying to run Ruby on my Mac. I installed it using RVM. But when I type it in, it gets stuck on the command prompt, like its waiting. The same happens with the default. I have no idea why this is happening. Running 10.7.3. Any ideas?

Answer 1

It is waiting, and it’s waiting for input. The ruby command takes in input till it receives the EOF character, and then executes it. Typically you pass it a file to run or pipe to stdin.

Perhaps you’re trying to run interactive Ruby (IRb)? In which case you should run irb.
