gem install nokogiri

The mirrors probably aren’t updated yet.

Congratulations on the JRuby support! Nokogiri has to be one of the #1
most requested items for us. And hopefully over the summer we’ll get a
Java+Ruby(+ no C at all) version released too!

gem install nokogiri

The mirrors probably aren’t updated yet.

But it still doesn’t work under mingw version of Ruby 1.9.1. It’s very
frustrated when you need testing app using webrat :-|…

Do you mind expanding on this? I tested it with that particular version
of ruby on windows, so I’m surprised it doesn’t work. As of 1.3.0, we
support that version, so if it doesn’t work, I consider that a bug.

People,

I had problems getting v1.2.3 installed so for this version I firstly
uninstalled the previous version. This time the gem install went OK and
“gem list” gives:

nokogiri (1.3.0)

but when I run the demo program I get:

./t095.rb:3:in `require’: no such file to load – nokogiri
(LoadError)

and the same from irb:

irb
irb(main):001:0> require ‘nokogiri’
LoadError: no such file to load – nokogiri
from (irb):1:in `require’
from (irb):1

What now?

Thanks,

Phil.

That works - thanks! - shouldn’t the line “require ‘rubygems’” be in the
example code on:

http://nokogiri.rubyforge.org/nokogiri/

?

Yes, but that’s a FAQ for every ruby gem out there. The root
documentation for
all gems should contain that line, but El Goog will always be able to
help if
they don’t.

It might be, but I get tripped up by “require ‘rubygems’” every few
months anyway.

When can RubyGems merge with Ruby? Or can’t it?

It is in 1.9.

For Ruby 1.8, setting the environment variable RUBY_OPTS to “-
rubygems” pretty much does what you want.

Of course…

I copied libxml, libxslt* to ruby installation manually.

ERROR: Error installing nokogiri:
nokogiri requires Ruby version ~> 1.8.0

I tried to use rake-compiler on OpenSUSE and Debian with Ruby 1.9.1 (in
system) and it failed on frex error. I tried to use it again with Ruby
1.8 (in system). Nokogiri didn’t find ruby header files (I installed
every ruby dev package)

The result is the nokogiri is impossible to install on Windows with Ruby
1.9.1. Yeah, I’m not a rocket scientist :frowning:

no windows love for me, even with 1.8.6

Okay. It shouldn’t try to compile anything. I will take a look because
this should “just work”.

Hi! It should be working now. I accidentally messed up the gem spec
platform string. I’ve uploaded a new gem to rubyforge, and was able to
install it on windows.

Let me know how this one works out!

I have localized Windows so I can’t send exact message in a popup window
but there was something like:

Input point of the procedure DllMain@12 hasn’t succeeded find the
dynamic library msvcrt-ruby191.dll.

I think there is conflict between mingw and mswin version of Ruby.

Can you point me to the 1.9.1 version you installed? I will install it
and see if I can debug it. Nokogiri is cross compiled with mingw, so
I’m surprised it isn’t working.
