Rails gem install failure

I updated my rubygems to 0.8.1, then tried to install rails and got this
failure. What am I doing wrong?

Thanks!

In both instances you are trying to do a "local" install, which means you are trying to install from a gem repository that is on the same machine. You want to do a remote install.

"gem install --remote rails" should do what you want

Did you run "update_rubygems" after you installed the "rubygems-update" gem?

Per Chad's 0.8.x instructions:

$ gem install rubygems-update
$ update_rubygems

We will fix this two-step process in the future.

"gem install --remote rails" should do what you want

I don't think so. See the line I highlighted above. The 'undefined method'
error is the actual problem.

From the output I think 0.8.1 gems tries local, then attempts remote. The
failure message was from an undefined method.

I tried your command line and it die not work (with 0.8.1). I tried
  gem -Ri rails
and got the same undefined method failure.

Other ideas?

Did you run "update_rubygems" after you installed the "rubygems-update"

gem?

Just did, and it helped.

The "rails" installation went smoothly except for these 2 errors/warning
while installing RDoc. Do I have a proper install of Rails?

Thanks!

Right...those are rdoc messages...they are not really errors.

So yes, you should not have a proper installation of rails.

error is the actual problem.

If the gem command isn't complaining about the '-i' on the base gem
command, then you are running an old version of gems. You need to upgrade
to 0.8.1 and try again. (I would suggest upgrading by loading the
rubygems tar or zip file and running "ruby install.rb". Your gem install
may be old enough that it has problems with some of the newer gem spec
fields.)
