macos - "No such file or directory - getcwd" error on rubygems on Mac Os Lion

Question

I'm trying to launch a heroku console that uses rubygems but I keep getting this error:

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:471:in `expand_path': No such file or directory - getcwd (Errno::ENOENT)
    from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:471:in `find_files'
    from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:470:in `map'
    from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:470:in `find_files'
    from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:1103
    from /usr/bin/heroku:9:in `require'
    from /usr/bin/heroku:9

I'm using Mac OS Lion 10.7.3. Any ideas on how to fix this? Thanks!

Maybe the current working directory of the shell that's used to start your heroku process doesn't exist (maybe removed by another process, as in my case), and therefore getcwd throws an error.
