ruby on rails 3 - rake db:migrate returns "rake: Is a directory"? -

-

i've been searching answer question week, haven't found one. i'm running mac os 10.5.8 if that's relevant.

i'm trying peepcode tutorial "meet rails 3" when run command line user$ rake db:migrate following error message:

/usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake: directory - /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake (errno::eisdir) /usr/local/bin/rake:19:in `load' /usr/local/bin/rake:19

i found exact same error @ ruby.pastebin.com no answer. willing out aspiring developer. thanks.

it looks using default install of ruby interpreter came mac os x. suggestion use rvm install/manage gem locations. haven't read/watched "meet rails 3" stuff, not sure advocating, can speak experience rvm makes these types of issues go away.
