Where are the sources for rails-2.3.5 and rack-1.0

问题:

I'm trying to upgrade a rails application which requires rails-2.3.5 which in turn seems to require rack-1.0.1. Many (many!) attempts of each of the following hasn't worked:

# gem install rails -v=2.3.5
ERROR:  could not find gem rails locally or in a repository

or

# gem install rails -v=2.3.5 --source http://gems.rubyforge.org
WARNING:  RubyGems 1.2+ index not found for:
    http://gems.rubyforge.org/

RubyGems will revert to legacy indexes degrading performance.
Bulk updating Gem source index for: http://gems.rubyforge.org/
ERROR:  While executing gem ... (Gem::RemoteSourceException)
    Error fetching remote gem cache: SocketError: getaddrinfo: Name or service not known (http://gems.rubyforge.org/yaml)

or substituting http://gems.rubyonrails.org. When I tried http://gems.github.org I get an index error.

Simply trying a gems update rails succeeds as a command, but it installs version 2.3.3.

Why would any of this not be working?

For reference:

# cat /root/.gemrc
---
:benchmark: false
:verbose: true
:update_sources: true
:sources:
- http://gems.rubyonrails.org
- http://gems.opscode.com
:bulk_threshold: 1000
:backtrace: false

(Is the installer really at version 2?)

回答1:

I came back two (2) hours later and:

# gem install rails -v=2.3.5 --source http://gems.rubyforge.org
Successfully installed activesupport-2.3.5
Successfully installed activerecord-2.3.5
Successfully installed rack-1.0.1
Successfully installed actionpack-2.3.5
Successfully installed actionmailer-2.3.5
Successfully installed activeresource-2.3.5
Successfully installed rails-2.3.5
7 gems installed
...

It worked.

Truly weird. It would be nice if the error messages could be a little more informative.
