Installation error


I’m having a problem installing rails on OS X 10.4.

I installed RubyGems 0.9.5 and when I use the command “gem install
rails --include-dependencies” I receive the following output:

INFO: gem install -y is now default and will be removed
INFO: use --ignore-dependencies to install only the gems you list
Bulk updating Gem source index for:
ERROR: While executing gem … (TypeError)
cannot convert nil into Array

Web and newsgroup searches haven’t returned much information.

Any ideas what the problem is?


Tried again after startup. Today’s message was:

Could not find rails (> 0) in any repository

This was more googlable than the other error, and revealed the

gem cleanup
sudo gem update

Then I was able to run the original rails install command

Including here in case others encounter the same problem.
