I am getting the follow error after running the following command. Any ideas?

$ rake gem:install

$ rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+)
$ rake aborted!


$ rake gem:install --trace

Look at the first lines in your Rakefile. Change:

require 'rake/rdoctask'

To:

require 'rdoc/task'

Edit:

It looks like you have a Rubygems incompatibility issue, like James suspects. You need to upgrade your Rails version, or downgrade your gem version.

You can change to any gem version with:

gem update --system x.y.z

I am using Ruby 1.8.7 and Rails 2.3.8 and getting the very same error. So I changed my RubyGems version to 1.5.3 and the issue solved. So what you need to do is to write this command: "gem update --system 1.5.3" It will update your ruby gems version to 1.5.3 which is fully working with rails 2.3.8. Hope it helps.

Which version of rubygems do you have? To use 2.3.5 you might need to use rubygems that <= 1.4 and rake 0.8.7.
