[Rubygems-developers] Problem while installing the Gems with tests from remote gem-server

[TANAKA Shin-ya]

Hi all,

I got following error while installing the Gems
with tests from remote gem-server.

$ sudo gem install -t trie
Attempting local installation of 'trie'
Local gem file not found: trie*.gem
Attempting remote installation of 'trie'
Successfully installed trie-0.0.1
Installing RDoc documentation for trie-0.0.1...
/usr/pkg/lib/ruby/site_ruby/1.8/rubygems.rb:204:in `report_activate_error': Could not find RubyGem trie (= 0.0.1) (Gem::LoadError)

        from /usr/pkg/lib/ruby/site_ruby/1.8/rubygems/gem_runner.rb:13:in `run'
        from /usr/pkg/bin/gem:17

In this case, installed gem isn't registered to Gem#source_index.
Gem#source_index is cached at RemoteInstaller#install(rubygems/remote_installer.rb:399).

To resolve this error, apply following patch.

I think it's ugly patch.
Please suggest better solutions.
