问题描述
我想看看黄瓜的Jruby在Rails。
I'm trying to look at cucumber for Jruby on Rails. One of the pre-requesites is webrat which has as pre-requisite hpricot.
我用hpricot安装了这个gem:
I've installed the gem with hpricot using:
gem install hpricot --source --version 0.6.1 --platform java
gem install hpricot --source http://code.whytheluckystiff.net --version 0.6.1 --platform java
这将安装hpricot的java版本。我将hpricot_scan.jar添加到CLASSPATH,但是当我运行时:
This installs the java version of hpricot. I add the hpricot_scan.jar to the CLASSPATH but when I run:
cucumber features -n
我得到以下输出:
HpricotScanService.java:931:in `hpricot_scan': java.lang.NoSuchMethodError:
org.jruby.runtime.builtin.IRubyObject.getInstanceVariable(Ljava/lang/String;)Lorg/jruby/runtime/builtin/IRubyObject;
from HpricotScanService.java:1324:in `__hpricot_scan'
from null:-1:in `call'
from InvocationCallback.java:67:in `execute'
from FullFunctionCallbackMethod.java:69:in `call'
from DynamicMethod.java:243:in `call'
from CachingCallSite.java:283:in `cacheAndCall'
from CachingCallSite.java:121:in `callBlock'
等。
如果我编译HpricotScanService.java文件并将生成的.class文件添加到类路径,我会得到:
If I compile the HpricotScanService.java file and add the resulting .class file to the classpath, I get:
Then I should see "Run"
private method `scan' called for Hpricot:Module (NoMethodError)
features/step_definitions/webrat_steps.rb:94:in `/^I should see "([^\"]*)"$/'
features/manage_activity.feature:9:in `Then I should see "Run"'
b $ b
如果我尝试安装hpricot的更高版本,那么我会得到:
If I try to install later versions of the hpricot, then I get:
ERROR: Failed to build gem native extension.
C:/Program Files/Ruby/jruby-1.2.0/bin/../bin/jruby.bat extconf.rb install hpricot --platform java

任何人都有任何线索
使用Windows XP,JRuby 1.2.0

推荐答案
FYI,1.4版的JRuby现在支持0.7版本的HPricot。
