Description (last modified by monvural) (diff)

I recently attempted to use HPricot on a new install of Ubuntu. You can see my IRB session here:

irb(main):004:0> require 'hpricot'
=> false
irb(main):005:0> doc = Hpricot("<p>A simple <b>test</b> string.</p>")
NoMethodError?: private method `scan' called for Hpricot:Module
from /usr/lib/ruby/gems/1.8/gems/hpricot-0.4.47/lib/hpricot/parse.rb:22:in `make'
from /usr/lib/ruby/gems/1.8/gems/hpricot-0.4.47/lib/hpricot/parse.rb:11:in `parse'
from /usr/lib/ruby/gems/1.8/gems/hpricot-0.4.47/lib/hpricot/parse.rb:4:in `Hpricot'
from (irb):5

The same error occurs in the release and 0.4.47 versions. I am running ruby 1.8.4, and will gladly supply you with more information as you request it

Hello guys,

Reddaly is not the only one in this situation. At least two more are: (see here). I'm following this ticket since... humm... a week ago. ;)

I tried

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'hpricot'
=> true
irb(main):003:0> require 'hpricot_scan'
=> false
irb(main):004:0>

and

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'hpricot_scan'
LoadError: /usr/lib/ruby/gems/1.8/gems/hpricot-0.4/lib/hpricot_scan.so: ELF file OS ABI invalid - /usr/lib/ruby/gems/1.8/gems/hpricot-0.4/lib/hpricot_scan.so        from /usr/lib/ruby/gems/1.8/gems/hpricot-0.4/lib/hpricot_scan.so
        from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:33:in `require'
        from (irb):2

I hope it will help.

I am runnning Ubuntu Dapper Drake, with Ruby 1.8.4 and Hpricot 0.4, and am having similar issues.

/usr/lib/ruby/gems/1.8/gems/hpricot-0.4/lib/hpricot/parse.rb:19:in make': private method scan' called for Hpricot:Module (NoMethodError?)

from /usr/lib/ruby/gems/1.8/gems/hpricot-0.4/lib/hpricot/parse.rb:11:in `parse' from /usr/lib/ruby/gems/1.8/gems/hpricot-0.4/lib/hpricot/parse.rb:4:in `Hpricot' from /home/michael/ruby_work/Ruby-1.rb:7

With hpricot-scan included, I get...

/usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- hpricot-scan (LoadError?)

from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /home/michael/ruby_work/Ruby-1.rb:4

I'd be happy to provide any other information.

I had exactly the same problem on the same setup, which is how I found this bug. The problem turned out to be that it never built the .so (this is a fresh dapper install, so I didn't have make installed).

Select which gem to install for your platform (i486-linux)
 1. hpricot 0.4 (ruby)
 2. hpricot 0.4 (mswin32)
 3. Cancel installation

Building native extensions.  This could take a while...
/usr/lib/ruby/1.8/fileutils.rb:243: command not found: make
/usr/lib/ruby/1.8/fileutils.rb:243: command not found: make install
/usr/lib/ruby/1.8/fileutils.rb:243: command not found: make clean
ruby extconf.rb install hpricot
checking for main() in -lc... yes
creating Makefile

make

make install

make clean
Successfully installed hpricot-0.4

I didn't notice the errors and just noticed the "success" at the end.

I think the proper fix is to make this install complain more loudly.

I have hpricot 0.5 functioning just swimmingly on my other Ubuntu box, so I'll report back here when I determine the offending difference.

Well, I never really determined the root cause of the problem, but I did manage to fix it... which is just as well, I suppose. I eventually just uninstalled gems and reinstalled hpricot, and the error disappeared.

If you're encountering the same error on Ubuntu and would like to follow the same procedure, read on...

First, you'll want to record a list of all your installed gems:

$ gem list > installed-gems.txt

Then, you should wipe all trace of gems:

$ rm -rf /usr/lib/ruby/site_ruby/1.8/rubygems*
$ rm -rf /usr/lib/ruby/gems/

From there on out it's simply a matter of reinstalling gems itself and then reinstalling each individual gem.
