RubyGems install

◆環境
Ubuntu 8.10
ruby 1.8.7

◆install
最初に...aptでgemを入れるのは大変危険な模様...
めんどくさくてもgemは手動で入れる方が良いみたい。

Rails入れようと思うたが、Gemを1.3.6に上げろと言われ...
apt-getしても1.3.5しか入ってくれなかったので手動でrubyとgemを導入してみる。

Gemsの事はRubyForgeを見るのが手っ取り早い。
http://rubyforge.org/projects/rubygems/

ココを見ると、現在の最新Verは1.3.7らしい。
で、downloadを試みるとこんな画面になる。

#ref error ：ご指定のファイルが見つかりません。ファイル名を確認して、再度指定してください。 (rubygems_dl.png)

『rubygems-1.3.7.tgz』はtar gzipでlinuxとか用、『rubygems-1.3.7.zip』はzip圧縮でWin用。
『rubygems-update-1.3.7.gem』はgemで使えるinstallerらしい。
確か『sudo gem install hoge -l』みたいな感じでイケルっての見た気がするが、また今度。

とりあえず、今回は『rubygems-1.3.7.tgz』を取得。

> wget http://rubyforge.org/frs/download.php/70696/rubygems-1.3.7.tgz

解凍。

> tar zxvf rubygems-1.3.7.tgz

install。

> cd rubygems-1.3.7/
> sudo ruby setup.rb

installできたっぽぃ。

RubyGems 1.3.7 installed

=== 1.3.7 / 2010-05-13

NOTE:

http://rubygems.org is now the default source for downloading gems.

You may have sources set via ~/.gemrc, so you should replace
http://gems.rubyforge.org with http://rubygems.org

http://gems.rubyforge.org will continue to work for the forseeable future.

New features:

* `gem` commands
* `gem install` and `gem fetch` now report alternate platforms when a
matching one couldn't be found.
* `gem contents` --prefix is now the default as specified in --help. Bug
#27211 by Mamoru Tasaka.
* `gem fetch` can fetch of old versions again. Bug #27960 by Eric Hankins.
* `gem query` and friends output now lists platforms. Bug #27856 by Greg
Hazel.
* `gem server` now allows specification of multiple gem dirs for
documentation. Bug #27573 by Yuki Sonoda.
* `gem unpack` can unpack gems again. Bug #27872 by Timothy Jones.
* `gem unpack` now unpacks remote gems.
* --user-install is no longer the default. If you really liked it, see
Gem::ConfigFile to learn how to set it by default. (This change was made
in 1.3.6)
* RubyGems now has platform support for IronRuby. Patch #27951 by Will Green.

Bug fixes:

* Require rubygems/custom_require if --disable-gem was set. Bug #27700 by
Roger Pack.
* RubyGems now protects against exceptions being raised by plugins.
* rubygems/builder now requires user_interaction. Ruby Bug #1040 by Phillip
Toland.
* Gem::Dependency support #version_requirements= with a warning. Fix for old
Rails versions. Bug #27868 by Wei Jen Lu.
* Gem::PackageTask depends on the package dir like the other rake package
tasks so dependencies can be hooked up correctly.
