我正在尝试在Ubuntu 10.04上安装RSRuby。我几乎不知道要报告哪些错误消息是相关的; 我已经在谷歌上搜索了数个小时，尝试的所有命令都无法解决问题。
以下是一些示例错误消息：
以下是一些示例错误消息：

或者使用apt-get进行操作：

我也从GitHub获取了最新的RSRuby，并按照其2006年PDF手册的说明进行操作：

在 irb 中：
irb(main):002:0> require 'RSRuby'
LoadError: no such file to load -- RSRuby
from (irb):2:in `require'
from (irb):2
from :0
irb(main):003:0> rsruby
NameError: undefined local variable or method `rsruby' for main:Object

有时候我看起来似乎能够得到一些看起来像是可行的东西，但仍然无法在irb命令行中加载rsruby。
$ sudo gem install rsruby --include-dependencies -- --with-R-dir=/usr/lib/R --with-R-lib=/usr/lib/R --with-R-include=/usr/share/R/include/

Ruby 的版本是 1.8.7，我今天使用了 sudo apt-get install ruby1.8-dev 命令，但我不确定这是否会让情况变得更糟、更好或者没有变化。或者在 ruby1.9 中更容易解决。
R 可以正常工作。
gem install rsruby -- --with-R-dir=$R_HOME请执行上述命令以安装rsruby，并确保将$R_HOME替换为您的R目录路径。 - s2t2
