Rails 3.2 на ошибках JRuby gemspec

Question

Когда я пытаюсь установить Rails 3.2 rc 1 на JRuby 1.6.5, я получаю эту ошибку gemspec:

Invalid gemspec in[/Users/robin/.rvm/gems/jruby-1.6.5/specifications/railties-3.2.0.rc1.gemspec]:
Illformed requirement ["#<YAML::Yecht::DefaultKey:0x469c3554> 3.2.0.rc1"]

Кажется, что у всех базовых гемов rails есть эта проблема, есть идеи?

Answer 1

На самом деле, Чарли и я разработали исправление, и теперь оно решено. https://github.com/jruby/jruby/commit/71bcb3941dcfe0e0d0217921b06ec66a421f2288

Фиксированная версия должна быть доступна завтра утром в http://ci.jruby.org/snapshots/

Answer 2

Попробуйте запустить JRuby в режиме 1.9. Файл gemspec Rails (и, возможно, других?) Неправильно анализируется yecht (старым совместимым с syck механизмом YAML). psy (новый, доступный в режиме 1.9) должен справиться с этим. Поскольку похоже, что у syck MRI есть схожая проблема с gemspec, я подозреваю, что MRI 1.8 также не может установить рельсы.

Например:

$ GEM_HOME=$HOME/gems GEM_PATH=$GEM_HOME jruby --1.9 -S gem install rails -v 3.2.0.rc1

Depending on your version of ruby, you may need to install ruby rdoc/ri data:

<= 1.8.6 : unsupported
 = 1.8.7 : gem install rdoc-data; rdoc-data --install
 = 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!
