I cd’d to the directory the error says ruby.h should be in, but I don’t see anything..

Edit: Added rvm info

GacntMac in /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby
o rvm info                                                    (Tue, Feb 05)
-bash: rvm: command not found

This is weird cause I’ve been playing with Rails for days, now it some how uninstalled its self?

This only started happening since I exited out of terminal and re-opened it. I’m lost and new to Rails so I have no idea what any of this means, just trying to follow a tutorial. Thanks!

Answer 1

You are trying to install software into the system installation of Ruby, put there by Apple.

RVM or rbenv will install things into a private sandbox in your home directory. The error shows the file isn’t going there, so your RVM or rbenv isn’t initialized correctly.

If you run RVM, execute rvm info from the command-line, and look at the information output, as a sanity check.
