rubygems and CentOS 4.4

Brian Candler

2/23/2007 2:31:00 PM

Something very strange has happened for me, and I'd like to know if I'm
doing something stupid.

I wanted to install activerecord, and to do so I thought it would be a good
idea to install rubygems to do the work for me. So I downloaded
rubygems-0.9.2 from http://rubyforge.org/frs/?group_id=126&relea...,
did "ruby setup.rb" as root. This seemed to start OK but then gave some
errors:

...
setup.rb:18:15: Couldn't find File. Assuming it's a module

test/functional.rb:158:0: Unrecognized directive 'section'
hook /v/build/rubygems-0.9.2/./post-install.rb failed:
undefined local variable or method `size' for #<SM::ToFlow:0xb7a6d230>
Try 'ruby setup.rb --help' for detailed usage.

I then tried "gem install activerecord" and it failed immediately:

ERROR: While executing gem ... (Gem::GemNotFoundException)
Could not find activerecord (> 0) in any repository

even though "gem query --remote --name-matches active" worked and showed the
gem. The full transcript of what I did is shown below.

This is running under CentOS-4.4 which currently has only ruby 1.8.1:

[root@localhost rubygems-0.9.2]# cat /etc/redhat-release
CentOS release 4.4 (Final)
[root@localhost rubygems-0.9.2]# ruby -v
ruby 1.8.1 (2003-12-25) [i386-linux-gnu]

Now, while I was composing this mail, I tried again, firstly with a smaller
package:

[root@localhost rubygems-0.9.2]# gem install redcloth
Successfully installed RedCloth-3.0.4
[root@localhost rubygems-0.9.2]# gem install activerecord
Install required dependency activesupport? [Yn] y
Successfully installed activerecord-1.15.2

Installing RDoc documentation for activerecord-1.15.2...
ERROR: While executing gem ... (NoMethodError)
undefined method `find_module_named' for nil:NilClass
[root@localhost rubygems-0.9.2]#

So it got further this time, but still bombed out in the end.

Any suggestions as to what I should do? I don't find this problem listed on
the rubygems FAQ at http://docs.rubygems.org/r... and neither do I
see any requirements saying that rubygems needs ruby version X.X.X to work.

Thanks,

Brian.

Another example which doesn't inspire much confidence:

As a comparison point: I just tried this on an Ubuntu-6.06 system. rubygems
itself installed without errors, but activerecord was not found on the first
attempt. The RubyInline gem gave a similar set of warnings, but not the
"unexpected token: '#<RubyToken::TkLPAREN:..." one I saw before. And a
second attempt to install activerecord was successful.

Regards,

Brian.

That looked a bit scary to me. But then I realised this was during rdoc
processing, so it's probably nothing to worry about.

Fwiw, I have been using the RPMs at
http://dev.centos.org/centos/4/testing/... on CentOS 4.1 and 4.4
without problems. You might want to give those a shot.

At this point, you should have stopped. Something is terribly wrong
with your ruby installation. Rubygems has NOTHING to do with this.
This has me worried.

You need 1.8.2 at the very least. Newer is better.

I would upgrade to a more recent version of Ruby. I had similar
problems on CentOS 4 and all were resolved when I simply build my own
ruby from source and no older than 1.8.4.

OK, I upgraded to these and now rubygems installs without bombing out.

Perhaps the rubygems webpage could be updated to say what the minimum Ruby
version is that it needs? Or it could test for this and give a warning/error
if you try to install it under a version which is too old?

Brian.
