ruby on railsインストールメモ（未解決）

ruby on railsのインストールと新規アプリの作成方法メモ。

[sohgoh@dev ~]$ sudo gem install rails

--snip--

Successfully installed rails-3.0.9
1 gem installed

インストールできたようだが、一部 "file 'lib' not found" とか言ってる...。どうもgemが古いようなので、アップデートしてみる。

[sohgoh@dev ~]$ gem -v
1.3.7
[sohgoh@dev ~]$ gem query -rn rubygems-update

*** REMOTE GEMS ***

rubygems-update (1.8.5)

[sohgoh@dev ~]$ sudo gem install rubygems-update
Successfully installed rubygems-update-1.8.5

[sohgoh@dev ~]$ sudo update_rubygems
RubyGems 1.8.5 installed

=== 1.8.5 / 2011-05-31

* 2 minor enhancement:

* The -u option to 'update local source cache' is official deprecated.
* Remove has_rdoc deprecations from Specification.

* 2 bug fixes:

* Handle bad specs more gracefully.
* Reset any Gem paths changed in the installer.


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

RubyGems installed the following executables:
/usr/bin/gem

[sohgoh@dev ~]$ gem -v
1.8.5
[sohgoh@dev ~]$

もう一回gem install railsしてみる。

[sohgoh@dev ~]$ sudo gem install rails

--snip--

Installing ri documentation for railties-3.0.9...
Installing ri documentation for bundler-1.0.15...
Installing ri documentation for rails-3.0.9...
file 'lib' not found
Installing RDoc documentation for activesupport-3.0.9...

--snip--

直ってない。orz

もう少し調べてみるとrdocを手動で入れなおすと良さそうなので試してみる。

[sohgoh@dev ~]$ gem -v
1.8.5
[sohgoh@dev ~]$ sudo gem install rdoc-data

Fetching: rdoc-2.5.11.gem (100%)
RDoc 2.5 did not save method parameters, so you should upgrade your rdoc-data
gem to a version >= 2.5.3.

To have ri data for core and stdlib you'll need to:

gem install rdoc-data

then run:

rdoc-data --install

To have ri data for you gems you'll also need to run:

gem rdoc --all --overwrite

If you don't want to rebuild the rdoc for `gem server`, add --no-rdoc.
Fetching: rdoc-data-2.5.3.gem (100%)
To install ri data for RDoc 2.5+ run:

rdoc-data

直らねー...orz
その後、railsのディレクトリにlibを作成すれば動作したという情報を参考に実施してみたけど、

[sohgoh@dev ~]$ cd /usr/lib64/ruby/gems/1.8/gems/rails-3.0.9/
[sohgoh@dev rails-3.0.9]$ ls
bin
[sohgoh@dev rails-3.0.9]$ sudo mkdir lib
[sohgoh@dev rails-3.0.9]$ ll

[sohgoh@dev gems]$ sudo gem install rails
