ruby インターン

会社のおはなしと環境構築でした！
私が借り受けたPCはたまたま、予めほとんどの環境が構築済みだったのでありがたかったです…。
gemのアップデートとrailsのアップデートを行ないました。

RoRの環境構築メモです。

C:\Documents and Settings\sea_mountain>rails --version
Rails 2.1.0

最新版にしましょう。

C:\Documents and Settings\sea_mountain>gem install rails --include-dependencies
INFO:  `gem install -y` is now default and will be removed
INFO:  use --ignore-dependencies to install only the gems you list
ERROR:  Error installing rails:
        actionpack requires rack (~> 1.1.0, runtime)

gemをアップデートさせないといけない感じ‥
参考サイト(http://www.gfd-dennou.org/arch/davis/gfdnavi/doc/install/install-rails.htm)

C:\Documents and Settings\sea_mountain>gem update
Updating installed gems
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    bad response Moved Permanently 301 (http://gems.rubyforge.org/latest_specs.4
.8)

確認

C:\Documents and Settings\sea_mountain>gem --version
1.2.0

ソースを取ってくる先を確認します。

C:\Documents and Settings\sea_mountain>gem sources
*** CURRENT SOURCES ***

http://gems.rubyforge.org/

登録されているアドレスを-rで削除したりしたのですが、結局

C:\Documents and Settings\sea_mountain>gem sources -a http://rubygems.org/
http://rubygems.org/ added to sources
C:\Documents and Settings\sea_mountain>gem sources
*** CURRENT SOURCES ***

http://rubygems.org/
C:\Documents and Settings\sea_mountain>gem update --system
Updating RubyGems
Updating rubygems-update
Successfully installed rubygems-update-1.3.7
ERROR:  While executing gem ... (NameError)
    undefined local variable or method `remote_gemspecs' for #<Gem::Commands::Up
dateCommand:0x34e78cc>

変なエラーが出る…

C:\Documents and Settings\sea_mountain>gem install rubygems-update
ERROR:  could not find gem rubygems-update locally or in a repository

やっぱり変なエラーが出る…

C:\Documents and Settings\sea_mountain>gem update
Updating installed gems
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    bad response Found 302 (http://rubygems.org/latest_specs.4.8)

もういちどlist表示してみると…

C:\Documents and Settings\sea_mountain>gem list

*** LOCAL GEMS ***
※省略
rubygems-update (1.3.7, 1.2.0, 1.1.1, 1.0.1)
※省略
C:\Documents and Settings\sea_mountain>gem --version
1.2.0

あれ？しかし、2つ上のgem listでは1.3.7が入っている！
ダウンロードは出来てたようです。
ので、以下のコマンドでインストールします。

C:\Documents and Settings\sea_mountain>update_rubygems

・ｿ=== 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.

RubyGems installed the following executables:
