Ошибки Java с jRuby on Rails в Google App Engine

Я следовал всем инструкциям с: http://code.google.com/p/appengine-jruby/wiki/RunningRails и http://gist.github.com/268192

В настоящее время я просто пытаюсь добраться до hello world. Я получаю эти ошибки, когда просто запускаю dev_appserver.rb

238:hello-world jwang392$ dev_appserver.rb .

The server is running at http://localhost:8080/

Я в недоумении, какой шаг я мог пропустить. Я проверил свою версию ruby ​​(1.8.7) и версию rails (2.3.5), версию gem (1.3.6) и google-appengine-0.0.10.1.

побежал:

sudo gem установить google-appengine

curl -O http://appengine-jruby.googlecode.com/hg/demos/rails2/rails2_appengine.rb

рубиновые рельсы2_appengine.rb

sudo gem установить rails_dm_datastore

sudo gem установить активную запись-nulldb-адаптер

поместите это в мой файл config.ru:

запустить лямбда { | env | Rack::Response.new('Привет, мир!').finish }

и, наконец, запустил $ dev_appserver.rb.

В порядке. В группе Google мне помог Джон Вуделл.

Для Rails вы должны следовать инструкциям по сути. Для приложения hello world сделайте следующее...

$ appcfg.rb generate_app hello-world  
$dev_appserver.rb hello-world

Я в недоумении, какой шаг я мог пропустить. Я проверил свою версию ruby ​​(1.8.7) и версию rails (2.3.5), версию gem (1.3.6) и google-appengine-0.0.10.1.

sudo gem install google-appengine
curl -O http://appengine-jruby.googlecode.com/hg/demos/rails2/rails2_appengine.rb
ruby rails2_appengine.rb
sudo gem install rails_dm_datastore
sudo gem install activerecord-nulldb-adapter

поместите это в мой файл config.ru:

run lambda { |env|Rack::Response.new('Hello World!').finish }

и, наконец, запустил
$ dev_appserver.rb .

В порядке. Я следил за всем и все же столкнулся с проблемой. Разобрался в чем дело. Я начал создавать папки проекта и столкнулся с unix fun-problem-land из-за того, что мне не нравились каталоги с пробелами в именах. как только я избавился от пробелов, все пошло нормально. Боже, прямо сейчас я чувствую себя настоящей дурой.
