I have been learning Ror, and developing my first application. I unfortunately am also relatively new to the mac, so please forgive my ignorance if I did something blatantly ridiculous.
I have been using rails 2.2.2. I learned about accepts_nested_attributes_for this morning, and realized I had to update my version of rails.
I first performed a gem update. I cant recall the exact command I invoked at this particular moment, but I believe it was rake rails:update. There was an installation warning, and the installer commented that it was installed in the following directory:
/Users/triguy_nc/.gem/ruby/1.8/bin
Being totally stupid, I figured - heck, this isnt goign to work, so I inserted the above into my $PATH in .profile. I actually thought the rake rails:update would have updated my version of rails (I was in a working directory when I did this)
I then issued the following command: gem install -v=2.3.5 rails
I received the following error message after the install:
WARNING: Installing to ~/.gem since /Library/Ruby/Gems/1.8 and /usr/bin aren't both writable. Successfully installed rails-2.3.5 1 gem installed Installing ri documentation for rails-2.3.5...

When I issue $PATH at teh command prompt, I receive the following response:
-bash: /Users/triguy_nc/.gem/ruby/1.8/bin:/opt/local/bin:/opt/local/ sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/ usr/X11/bin: No such file or directory
So, I am basically hosed, but do think I can revert to 2.2.2 in my environment.rb. BUT, I really need to learn some basics of what I am trying to do.
Questions:
1. Can someone give me some guidance to undo my errors above, and repair my system so the installation is proper? 2. Can you also point me to a tutorial to help me to understand the method to update rails, so I dont make the same hack mistakes again.
Thanks
