Hi all, this is my first post but I am hoping you all can help me here. I know my way around computers, but apparently not as much as I thought. I finally upgraded to 10.7.3 last night, and also downloaded XCode as well. I wanted to pursue Ruby/RoR so I went to the Aptana site and downloaded the Aptana studio from the website. I downloaded git and installed it, and I figured I was good to go. So with RVM install it lays it out pretty straightforward, or so I thought. I tried $ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer) but it then says "-bash: $: command not found" So I did a sudo command, and that installed it (I think, I can't find it anywhere). But it won't work for ANY OTHER command. Everything comes up as "command not found". It shows that git is located in usr/local, so does anybody have any idea as to what the problem may be, and what I can do? I really want to get started on learning Ruby and not spending my whole Saturday figuring out some error that I couldn't even begin to figure out on my own. Many thanks!!
