Я пытаюсь установить RSRuby в Ubuntu 10.04.Я даже не знаю, какие сообщения об ошибках сообщать как соответствующие;Я просто гуглю несколько часов, и ни одна из команд, которые я пытаюсь решить, не решает проблему.
Вот несколько примеров сообщений об ошибках:
$ sudo gem install rsruby -- --with-R-dir=/usr/lib/R
Building native extensions. This could take a while...
ERROR: Error installing rsruby:

или выполнение с apt-get:

Я также получил последнюю версию RSRuby от GitHub и следовал инструкциям из руководства PDF 2006 года:
$ ruby setup.rb config -- --with-R-dir=/usr/lib/R

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

и irb:

Иногда мне кажется, что я могу получить что-то похожее на работу, но все равно не могу загрузить rsruby из командной строки irb.

Ruby - это версия 1.8.7, я сделал sudo apt-get install ruby1.8-dev сегодня, но я не уверен, что это оставило вещи хуже, лучше или без изменений.Или, если это будет проще, то ruby1.9.
R работает.
