Question

我正在尝试使用savon Gem，以便与webServices交互。所以我安装了它，似乎安装还可以：

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

我可以使用简单的命令测试它：

ruby -rubygems -e 'require "savon"'

（感谢此提示我没有更多错误http://wiki.mccune.org.uk/index.php/Backtrack）

当我想使用需要savon的.rb脚本时会出现问题：

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

/usr/lib/jruby//lib/ruby/site_ruby/shared/builtin/javasupport/core_ext/object.rb:75 warning: already initialized constant StartBurp

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

似乎存在环境问题，但我无法弄清楚如何解决它： - /

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

有没有人遇到同样的问题（我在上次发布时运行backtrack5）

感谢

看起来你有两颗红宝石，系统一（1.9.2dev）和jruby。当您运行ruby或gem时，它会选择系统ruby，而jruby -S buby命令会选择jruby。

如果你跑：

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

这应解决问题。
