rvm リハビリ
とりあえず、rails2.3.4 な環境を作りたい。手元にあるのは以下らしい。
$ rvm list rvm rubies ruby-1.8.7-p352 [ x86_64 ] => ruby-1.9.2-p180 [ x86_64 ] $ rvm gemset list gemsets for ruby-1.9.2-p180 (found in /home/hoge/.rvm/gems/ruby-1.9.2-p180) global keydown => rails3tutorial $
ええと、1.8.7 配下で 2.3.4 が使えれば良いのだろうか。
とりあえず
$ rvm use 1.8.7
しといて
$ sudo rake gems:install
してみるとどうなるのかな。あ、gemset 作っといた方が良いのか
rvm gemset create rails2.3.4
。あと gitosis-web-admin 配下に以下な .rvmrc を作成。
rvm use ruby-1.8.7-p352@rails2.3.4
で、rake gems install してみる。と `gem install -v=2.3.4 rails` しろ、って言われましたな。ご託宣に従いコマンド実行。
$ gem install -v=2.3.4 rails Fetching: activesupport-2.3.4.gem (100%) Fetching: activerecord-2.3.4.gem (100%) Fetching: rack-1.0.1.gem (100%) Fetching: actionpack-2.3.4.gem (100%) Fetching: actionmailer-2.3.4.gem (100%) Fetching: activeresource-2.3.4.gem (100%) Fetching: rails-2.3.4.gem (100%) Successfully installed activesupport-2.3.4 Successfully installed activerecord-2.3.4 Successfully installed rack-1.0.1 Successfully installed actionpack-2.3.4 Successfully installed actionmailer-2.3.4 Successfully installed activeresource-2.3.4 Successfully installed rails-2.3.4 7 gems installed
どうも --no-ri とか --no-rdoc とか忘れるな。とりあえずこれで rake gems install できるのかどうなのか。
$ rake gems install (in /home/hoge/Documents/rails_proj/gitosis-web-admin) rake aborted! uninitialized constant ActiveSupport::Dependencies::Mutex /home/hoge/Documents/rails_proj/gitosis-web-admin/Rakefile:10 (See full trace by running task with --trace) $
gem のバージョンが微妙なのか。ココによると 1.3.7 と記述があるのでそれに沿ってみる。
$ gem update --system 1.3.7 (中略 RubyGems system software updated $
で、リトライ。
$ rake gems install (in /home/hoge/Documents/rails_proj/gitosis-web-admin) rake aborted! No such file or directory - /home/hoge/Documents/rails_proj/gitosis-web-admin/config/database.yml (See full trace by running task with --trace) $
あ、、、
これは example をそのまま流用。
$ cp config/database.example.yml config/database.yml $ rake gems install (in /home/hoge/Documents/rails_proj/gitosis-web-admin) - [ ] configatron - [ ] git I = Installed F = Frozen R = Framework (loaded before rails starts) rake aborted! Don't know how to build task 'install' (See full trace by running task with --trace) $
あ、なんかもの凄いナチュラルをぶちカマシてますorz
リトライ。
$ rake gems:install (in /home/hoge/Documents/rails_proj/gitosis-web-admin) gem install configatron Successfully installed yamler-0.1.0 Successfully installed configatron-2.8.3 2 gems installed Installing ri documentation for yamler-0.1.0... Installing ri documentation for configatron-2.8.3... Installing RDoc documentation for yamler-0.1.0... Installing RDoc documentation for configatron-2.8.3... gem install git Successfully installed git-1.2.5 1 gem installed Installing ri documentation for git-1.2.5... Installing RDoc documentation for git-1.2.5... $
やれやれ。で、以下なコマンド実行してみたら
$ rake --rules (in /home/hoge/Documents/rails_proj/gitosis-web-admin) No such file or directory - /home/hoge/Documents/rails_proj/gitosis-web-admin/config/application.yml rake aborted! no such file to load -- sqlite3 (See full trace by running task with --trace) $
これも example しか無い。とりあえず先に gitosis 入れないと駄目かな。config/application.example.yml が以下。
$ cat config/application.example.yml # Settings that are the same for each environment global: &global gitosis_admin_root: /path/to/gitosis_admin_working_copy # Absolute path to your gitosis admin working copy remote_git_repository: git@yourhost.com # Where your repositories are hosted gitosis_config: gitosis.conf # You don't need to change this gitosis_keydir: keydir # You don't need to change this # Environment specific variables. # Just override global settings as needed. development: <<: *global production: <<: *global # Use tmp files during tests test: <<: *global gitosis_admin_root: <%= RAILS_ROOT+"/tmp/" %> gitosis_config: 'gitosis.conf.test' gitosis_keydir: 'keydir.test' $
とりあえず gitosis をローカルに入れる。
$ sudo apt-get install gitosis
で、初期化を手前ミソながら_ココ_を見つつ以下。
$ sudo -H -u gitosis gitosis-init < ~/.ssh/id_rsa.pub Initialized empty Git repository in /srv/gitosis/repositories/gitosis-admin.git/ Reinitialized existing Git repository in /srv/gitosis/repositories/gitosis-admin.git/ $
で、どこに clone しよう。あ、application.example.yml には_gitosis_admin_root_ってあるので /srv/gitosis ってことで良いのかな。や、working copy ってことなので、clone して云々なディレクトリなのか。
なので適当なディレクトリで以下。
$ cd ~/Documents $ git clone gitosis@localhost:gitosis-admin.git Initialized empty Git repository in /home/hoge/Documents/gitosis-admin/.git/ remote: Counting objects: 5, done. remote: Compressing objects: 100% (5/5), done. remote: Total 5 (delta 0), reused 5 (delta 0) Receiving objects: 100% (5/5), done. $
で、ここの絶対パスを書いてあげれば良いのか。コピーして
$ cp config/application.example.yml config/application.yml
編集 (一部のみ引用)。
global: &global gitosis_admin_root: /home/hoge/Documents/gitosis-admin # Absolute path to your gitosis admin working copy # remote_git_repository: git@yourhost.com # Where your repositories are hosted
で、rake --rules 確認。
$ rake --rules (in /home/hoge/Documents/rails_proj/gitosis-web-admin) rake aborted! no such file to load -- sqlite3 (See full trace by running task with --trace) $
あら。sqlite3 なパケジは導入済みのはずなのですがこれは一体何だろ。ちなみに導入済みなナニは以下。
$ dpkg --get-selections|grep sqlite libqt4-sql-sqlite install libsqlite0 install libsqlite3-0 install libsqlite3-dev install libsqlite3-ruby install libsqlite3-ruby1.8 install meego-sdk-libqt4-sql-sqlite install python-sqlite install python-sqlitecachec install sqlite3 install $
- dev とか -ruby なんてのも入ってるなぁ。あるいは以下。
$ dpkg --get-selections|grep ruby libruby install libruby1.8 install libsqlite3-ruby install libsqlite3-ruby1.8 install ruby install ruby1.8 install
ええと gem なのかなぁ。これで gem の導入が足らんとか言われると非常に辛いのですが。
$ gem search sqlite3 -r *** REMOTE GEMS *** activerecord-jdbcsqlite3-adapter (1.2.0, 1.0.3 java) dawanda-sqlite3 (1.3.3) dbd-sqlite3 (1.2.5) do_sqlite3 (0.10.7 ruby java x86-mingw32 x86-mswin32-60) fluent-query-sqlite3 (0.9.0) jdbc-sqlite3 (3.7.2, 3.6.14.2.056 java) rdbi-driver-sqlite3 (0.9.1) sqlite3 (1.3.4 ruby x86-mingw32 x86-mswin32-60) sqlite3-dotnet (3.7.2.1) sqlite3-ironruby (0.1.1) sqlite3-ruby (1.3.3, 1.3.2 x86-mingw32 x86-mswin32-60, 1.2.5 x86-mswin32, 1.2.3 mswin32) $

あらまあ。試験の数以上にエラーがあったりするあたり、微妙杉。rake test:units に至っては異常終了しておる始末。何が悪いのかなぁ。てか、ちゃんと動くの? これ。
む
なんとなく gem で入れたナニのバージョンが微妙なのかなぁ、と類推。面倒なので script/server してブラウザでアクセスしてみたら_We're sorry, but something went wrong._とのこと。
log/development.log に以下なソレが。

うーん。どうやら rvmからrailsを利用しようとすると'no such file to load -- openssl'のエラーというエントリによるとちょっとした操作が必要らしい。
だんだん面倒になってきたのですが、もう少し頑張ってみます。

とりあえず試験は動かぬが動作はする模様。
取り組みとして中身を精査しながら 3.x に移行させて rspec な試験も書く、というのは良いかもしれんが時間があるのかどうなのか。
今はとりあえず動くソレがあれば良いので。
