Permission denied when creating new rails app

Question

I'm getting a permission denied when attempting to create a new rails app - and I'm at a bit of a loss as to why. I installed Ruby 1.9.3 (I'm aware Mac OSX Lion ships with ruby, but an older version). When installing, I did not have to sudo.

Also, when installing rails, I did not sudo the gem install either.

It appears the only way I can create a new rails app is to sudo the comment though. Here is the trace of the error:

Can you run `mkdir /Users/bkosborne/Sites/test` without being denied? — Jeremy, Feb 23 '12 at 04:18
Might want to make sure that your `tmp` folder has permissions... maybe using `chmod 777 tmp`? (http://stackoverflow.com/questions/8127849/rails-3-1-errnoeacces-permission-denied) — summea, Feb 23 '12 at 04:19
ah wow. I've been doing this too long tonight... yeah the site's folder is owned by root and thus I was unable to create directories within it. I didn't even investigate that because I assumed it wasn't owned by root. Thanks! — Brian, Feb 23 '12 at 04:25

/Users/bkosborne/Sites/ doesn't exist or you don't have write permissions into that directory. chown the directory to yourself or chmod it so that you can write into it.
