さとうようぞうのblog

会社の開発環境（MacBookPro）のRailsを2.1.0に更新しようとして、Leopardのターミナルから

sudo gem update rails

したらとりあえずrails2.1.0にはなった。
が、Leopardに標準で着いているgem1.0.2は依存モジュールまではきっちりアップデートしてくれないようで（泣）、ActivesupportとかActiverecordも含めて全部手動で

sudo gem update activerecord

とかいう作業を延々と繰り返すハメになってしまった・・・・。

知識がないってのはホント痛いな。

割と最近CentOS5にソースからbuildして入れたgem1.2はupdate railsするだけでActiveSupportもActionMailerも全部更新されたから、Leopardのgemを更新しりゃぁいいんだ、と思ってhelpをみたら

Usage: gem update GEMNAME [GEMNAME ...] [options]

Options:
--system Update the RubyGems system software

こう書いてある。なるほどねー。
ということで早速実行。

= Announce: RubyGems Release 1.2.0

Release 1.2.0 adds new features and fixes some bugs.

New features:

* RubyGems no longer performs bulk updates and instead only fetches the gemspec
files it needs. Alternate sources will need to upgrade to RubyGems 1.2 to
allow RubyGems to take advantage of the new metadata updater. If a pre 1.2
remote source is in the sources list, RubyGems will revert to the bulk update
code for compatibility.
* RubyGems now has runtime and development dependency types. Use
#add_development_dependency and #add_runtime_dependency. All typeless
dependencies are considered to be runtime dependencies.
* RubyGems will now require rubygems/defaults/operating_system.rb and
rubygems/defaults/#{RBX_ENGINE}.rb if they exist. This allows packagers and
ruby implementers to add custom behavior to RubyGems via these files. (If
the RubyGems API is insufficient, please suggest improvements via the
RubyGems list.)
* /etc/gemrc (and windows equivalent) for global settings
* setup.rb now handles --vendor and --destdir for packagers
* `gem stale` command that lists gems by last access time

Bugs Fixed:

* File modes from gems are now honored, patch #19737
* Marshal Gem::Specification objects from the future can now be loaded.
* A trailing / is now added to remote sources when missing, bug #20134
* Gems with legacy platforms will now be correctly uninstalled, patch #19877
* `gem install --no-wrappers` followed by `gem install --wrappers` no longer
overwrites executables
* `gem pristine` now forces reinstallation of gems, bug #20387
* RubyGems gracefully handles ^C while loading .gemspec files from disk, bug
#20523
* Paths are expanded in more places, bug #19317, bug #19896
* Gem::DependencyInstaller resets installed gems every install, bug #19444
* Gem.default_path is now honored if GEM_PATH is not set, patch #19502

Other Changes Include:

* setup.rb
* stub files created by RubyGems 0.7.x and older are no longer removed. When
upgrading from these ancient versions, upgrade to 1.1.x first to clean up
stubs.
* RDoc is no longer required until necessary, patch #20414
* `gem server`
* Now completely matches the output of `gem generate_index` and
has correct content types
* Refreshes from source directories for every hit. The server will no longer
need to be restarted after installing gems.
* `gem query --details` and friends now display author, homepage, rubyforge url
and installed location
* `gem install` without -i no longer reinstalls dependencies if they are in
GEM_PATH but not in GEM_HOME
* Gem::RemoteFetcher now performs persistent connections for HEAD requests,
bug #7973

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: 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!

------------------------------------------------------------------------------

RubyGems installed the following executables:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/gem

If `gem` was installed by a previous RubyGems installation, you may need
to remove it by hand.

RubyGems system software updated

gem -vしてみると

$ gem -v

ちゃんと1.2.0に更新された。

これでrailsを更新してみると、

$ sudo gem update rails

依存モジュールも含めて一括updateに成功！！

gem --systemなんて全然知らなかったので、月一くらいでcronに仕込むようなスクリプトを作っておいた方がいいのかもしれないなぁ、と思ったり。
