Issue with ruby savon jruby

Question

我正在尝试使用savon Gem，以便与web服务交互。所以我安装了它，看起来安装还可以：

gem list savon
*** LOCAL GEMS ***
savon (1.2.0)

我可以用简单的命令进行测试：

ruby -rubygems -e 'require "savon"'

(多亏了这个提示，我再也没有错了http://wiki.mccune.org.uk/index.php/Backtrack)

当我想使用需要savon:的.rb脚本时，就会出现这个问题

jruby -S buby -i -B /pentest/web/burpsuite/burpsuite_v1.4.01.jar -r /home/fred/soapAtk2.rb

from /usr/lib/jruby/bin/buby:19

似乎存在环境问题，但我不知道如何解决：-/

ruby -r rubygems -e "p Gem.path"
["/root/.gem/ruby/1.9.2", "/usr/lib/ruby/gems/1.9.2"]
# gem content savon
/var/lib/gems/1.9.2/gems/savon-1.2.0/.gitignore
/var/lib/gems/1.9.2/gems/savon-1.2.0/.rspe
...
...

其他信息

# ruby -v
ruby 1.9.2dev (2010-07-02) [x86_64-linux]
# gem -v
1.3.7

有人遇到同样的问题吗(我运行回溯5上次发布)

谢谢

Answer 1

看起来有两个rubie，系统一个(1.9.2dev)和jruby。当您运行ruby或gem时，它会获取系统ruby，而jruby -S buby命令会获取jruby。

如果运行：

jruby -rubygems -e 'require "savon"'

这很可能会失败。

要在jruby实例上安装savon，请运行：

jruby -S gem install savon

这应该可以解决问题。
