Gems Install Problem

Hi

I just installed gems and after it 'successfully' installed,
it burped. Below are the stats:

I got this problem too. I think I found the fix. I dug around in the rubygems libraries. This is the line where the error comes from:

   lib/rubygems/specification.rb, line 474
     result << " s.#{name} = #{ruby_code(current_value)}\n" unless current_value == default

You can either setup a default:

   lib/rubygems/specification.rb, line 189
     required_attribute :version, Version.create('0.0.0')

Or you can make version's compare nicely to nihilism:

   lib/rubygems/version.rb, line 122
     def <=>(other)
       return 1 unless other # I figure something is always more than nothing

Either way, things worked for me. I've already forwarded this fix to the rubygems-developers mailing list.

Cheers,

Patrick

Jim, you're reporting 3 errors I haven't seen before. If you haven't
gotten help by the end of the day I'll take a look at all of this when
I get home. Busy day in the office today unfortunately.

Do a:

gem list

And ensure that the sources gem is present is present.

Likely you need to sudo to install rails though...

sudo gem install -r rails

Let us know the output of gem list...

Quickly looking at this, it appears that sources-0.0.1.gem is not
_readable_ by the user you're logged in as. Can you check the
ownership/permissions on that file in your rubygems install directory?

I don't know what this sources gem is. Was that supposed
to be part of the install?

We'll get to this later, but this system does not have sudo
and I don't have access to root, that is why I did the local

It's part of the rubygems installer. So, it should be in the
directory where you untarred the rubygems distribution.

BTW, I did a test with the same version of Ruby you were using,
installing into a local Ruby in my home directory (Fedora linux) and
wasn't able to reproduce the permissions problem.

I don't know what this sources gem is. Was that supposed
to be part of the install?

Yea, it's part of the install. "sources" is the list of remote
repositories. We package it as a gem (right now there's only one, but
doing it as a gem means we can update it remotely later with "gem
update" or "gem install sources").

We'll get to this later, but this system does not have sudo
and I don't have access to root, that is why I did the local
ruby install.

You shouldn't need sudo access if you're running a ruby that is
installed in a place you have access to. I just installed ruby 1.8.1,
rubygems 0.8.1, and then some gems into that local directory. There's
something amuck on your system (not necessarily your system's fault,
of course). Or you might have some part of your configuration in a
state that we haven't seen/tested with RubyGems. Let the hunt
continue :slight_smile: (Thanks for wading through this with us).

Other data that may help in the debug:

   > which ruby
   /disk2/jfn/usr/local/bin/ruby

I'm not sure if this would explain everything, but have you tried
running all of these with explicit full paths to your intended Ruby
interpreter?

   > ruby -v
   ruby 1.8.1 (2003-12-25) [i686-linux]

Same here.

   > which gem

   > gem -v
   0.8.1

Same here too.

   > gem list

Here, I see the sources gem installed, which should be present in
every rubygems installation.

This is because it's trying to go download the rails gem, but it can't
load the sources definition to see where to go get the rails gem from.
It's all caused by the permissions problem you have while running
install.rb

Thanks for your patience,
Chad

That was the problem. It was owned by root.
So, geneology was this:

1) Tried to install gems into /usr/local/ with su
2) #1 failed
3) Built and installed local version of ruby w/o root.
4) installed gems (failed)

So, if I had sudo and had used 'sudo ruby install.rb' to install
gems, would the permissions for source not been root?

This explains why #3 failed, but not #1.

That was the problem. It was owned by root.
So, geneology was this:

1) Tried to install gems into /usr/local/ with su
2) #1 failed

At this point, the sources gem was actually _built_ by the installer
(as root). It gets built from a specification whenever you run
install.rb. So the .gem file was generated as root and therefore
inaccessible (as per your umask) to other users.

3) Built and installed local version of ruby w/o root.
4) installed gems (failed)

So, if I had sudo and had used 'sudo ruby install.rb' to install
gems, would the permissions for source not been root?

This explains why #3 failed, but not #1.

I'm glad we know why #3 failed. I'm still unsure on #1. I see where
this is happening in the code, but it may take some more focused time
to track down how it could have gotten in this state.

Perhaps Gavin could help on this front, as the specification stuff is
probably best understood by him as of now.
