Ruby on Rails を導入

Ruby on Rails を導入してみようといくつかのサイトを見て apt-get で rubygems を入れたあと
gem install rails でOKなんて書いてあるから、楽勝と思って同じようにしてみても、どうも応答が帰ってこないでフリーズしてしまう。
メモリが192MBしかつんでいないので、それが原因かと思いながら、何回もトライ。
しょうがないので、ソースコードから入れることを決断し。ruby on Rails のサイトで rubugemsの1.3.1をダウンロードして,インストール。
この後、シンボリックリンクを
ln ?s /usr/bin/gem1.8 /usr/bin/gem

とした後、gem install rails でうまくインストールできそうな予感。

mkdir -p /usr/local/lib/site_ruby/1.8
mkdir -p /usr/bin

= Announce: RubyGems Release 1.3.0

NOTE:? RubyGems 1.1 and 1.2 have problems upgrading when there is no
rubygems-update installed.? You will need to follow the second set of update
instructions if you see “Nothing to update”.

Release 1.3.0 fixes some bugs.

Bugs fixed:

* Disregard ownership of ~ under Windows while creating ~/.gem.? Fixes
? issues related to no uid support under Windows.
* Fix requires for Gem::inflate, Gem::deflate, etc.
* Make Gem.dir respect :gemhome value from config.? (Note: this feature may be
? removed since it is hard to implement on 1.9.)
* Kernel methods are now private.? Patch #20801 by Stefan Rusterholz.
* Gem::location_of_caller now behaves on Windows.? Patch by Daniel Berger.
* Silence PATH warning.

Deprecation Notices:

* Gem::manage_gems will be removed on or after March 2009.

For a full list of changes to RubyGems and the contributor for each change, see
the ChangeLog file.

Special thanks to Chad Wooley for backwards compatibility testing and Luis
Lavena for continuing windows support.

== How can I get RubyGems?

NOTE:? If you have installed RubyGems using a package system you may want to
install a new RubyGems through the same packaging system.

If you have a recent version of RubyGems (0.8.5 or later), then all
you need to do is:

? $ gem update –system?? (you might need to be admin/root)

NOTE:? RubyGems 1.1 and 1.2 have problems upgrading when there is no
rubygems-update installed.? You will need to follow the second set of update
instructions if you see “Nothing to update”.

NOTE: You may have to run the command twice if you have any previosly
installed rubygems-update gems.

If you have an older version of RubyGems installed, then you can still
do it in two steps:

? $ gem install rubygems-update? (again, might need to be admin/root)
? $ update_rubygems????????????? (… here too)

If you don’t have any gems install, there is still the pre-gem
approach to getting software … doing it manually:

1. DOWNLOAD FROM: http://rubyforge.org/frs/?group_id=126
2. UNPACK INTO A DIRECTORY AND CD THERE
3. INSTALL WITH:? ruby setup.rb? (you may need admin/root privilege)

== To File Bugs

The RubyGems bug tracker can be found on RubyForge at:
http://rubyforge.org/tracker/?func=add&group_id=126&atid=575

When filing a bug, `gem env` output will be helpful in diagnosing the issue.

If you find a bug where RubyGems crashes, please provide debug output. You can
do that with `gem –debug the_command`.

== Thanks

Keep those gems coming!

— Jim & Chad & Eric (for the RubyGems team)
