JRuby OpenSSL错误 [英] JRuby OpenSSL Error

问题描述

我在配置JRuby以正确使用OpenSSL时遇到问题。谷歌搜索显示，这是一个相当常见的事件，但我读过的解决方案都没有为我工作。这里是我的设置：

• Ubuntu 9.10


• jruby 1.5.1


• jruby-openssl（0.7）
  

这是错误：

  irb（main）：001：0>需要'jruby / openssl / gem_only'
 => true 
 irb（main）：002：0>要求'openssl'
 => true 
 irb（main）：003：0> OpenSSL :: Digest :: OPENSSL_VERSION_NUMBER 
 NameError：未初始化的常量OpenSSL :: Digest :: OPENSSL_VERSION_NUMBER 
  

有趣的是，即使我没有安装jruby-openssl gem， require'openssl'也会返回true。根据这个链接，这不应该发生？

<试着用 require'rubygems'和 gem'jruby-openssl'来加载gem并没有帮助。

解决方案

你确定你正在寻找合适的常量？

  $ ruby​​ -v -r openssl -e'p OpenSSL :: Digest :: OPENSSL_VERSION_NUMBER'
 ruby​​ 1.8.7（2009-06-12 patchlevel 174）[universal- darwin10.0] 
 -e：1：未初始化的常量OpenSSL :: Digest :: OPENSSL_VERSION_NUMBER（NameError）
 
 $ ruby​​ -v -r openssl -e'p OpenSSL :: OPENSSL_VERSION_NUMBER'
 ruby​​ 1.8.7（2009-06-12 patchlevel 174）[universal-darwin10.0] 
 9470159 
 
 $ jruby -v -r openssl -e'p OpenSSL :: OPENSSL_VERSION_NUMBER'
 jruby 1.5.1（ruby 1.8.7 patchlevel 249）（2010-06-06 f3a3480）（Java HotSpot™64位服务器VM 1.6.0_20）[x86_64-java]

I am having problems configuring JRuby to work properly with OpenSSL. Googling has revealed that this is a pretty common occurence, but none of the solutions I've read have worked for me. Here is my setup:

• Ubuntu 9.10
• jruby 1.5.1
• jruby-openssl (0.7)

Here is the error:

irb(main):001:0> require 'jruby/openssl/gem_only'
=> true
irb(main):002:0> require 'openssl'
=> true
irb(main):003:0> OpenSSL::Digest::OPENSSL_VERSION_NUMBER
NameError: uninitialized constant OpenSSL::Digest::OPENSSL_VERSION_NUMBER

Interestingly, require 'openssl' returns true even if I don't have the jruby-openssl gem installed. According to this link, that shouldn't happen?

Trying to load the gem explictly with require 'rubygems' and gem 'jruby-openssl' doesn't help.

解决方案

Are you sure you are looking at the right constant?

$ ruby -v -r openssl -e 'p OpenSSL::Digest::OPENSSL_VERSION_NUMBER'
ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]
-e:1: uninitialized constant OpenSSL::Digest::OPENSSL_VERSION_NUMBER (NameError)

$ ruby -v -r openssl -e 'p OpenSSL::OPENSSL_VERSION_NUMBER'
ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]
9470159

$ jruby -v -r openssl -e 'p OpenSSL::OPENSSL_VERSION_NUMBER'
jruby 1.5.1 (ruby 1.8.7 patchlevel 249) (2010-06-06 f3a3480) (Java HotSpot(TM) 64-Bit Server VM 1.6.0_20) [x86_64-java]
