nokogirl on ubuntu: failed to build gem native extension

[Edouard Dantes]

Hi,

I want to give a try to nokogiri with mechanize as it seems to have
encoding methods.

I run ubuntu heron and installed the libraries libxslt1-dev libxml2
libxml2-dev.

now when i run sudo gem install nokogiri i get this error log:

ruby extconf.rb install nokogiri-1.1.1.gem
extconf.rb:3:in `require': no such file to load -- mkmf (LoadError)
from extconf.rb:3

I don't get what's missing here?

thanks for comments.

Search and install package named ruby-dev. Notice also that it's
nokogiri (last letter is 'i').

Search and install package named ruby-dev.

Have similar problem and tried to install ruby-dev but it is not in my
system
I am on linux ( CentOS release 5.2 (Final) How do I go about installing
it?

Tried it and also followed this site http://whomwah.com/tag/howto/ for
my specific OS to no avail. Maybe I need to modify the conf file (I
attached file with execution for review)
Thanks a bunch for all the help -- alice

Cheers--

Sorry, I lost the original, but there is a nokogirl gem:

$ gem list -r nokogir

*** REMOTE GEMS ***

nokogiri (1.2.3)
nokogirl (1.0)
$ gem dep -r nokogirl
Gem nokogirl-1.0
nokogiri (>=3D 0, runtime)

I tried it too and it's there. What's the point? Should we try to
install nokogirl instead?

IIRC, Mike Dalessio always typed "nokogirl" instead of "nokogiri", so =20=

he released "nokogirl"=

Since I was a small boy, I have always wanted to be famous for my poor
typing skills. So, I would love to sit back and let this particular piece of
urban mythology propagate.

However, nokogirl is just too damn funny to not give credit where it is due:

Carry on.

LOL -with tears in my eyes! Worked on a wget today, with the help of my
provider and it's a nice solution instead of the mechanize module I was
hoping to install from this nokogiri(l) or whatever. I'll keep trying
for my other data provider and ...Stay tuned!. In the meantime if
there's any ruby expert with a bit of time to review the attachement,
maybe I am missing something.

The issue on my installation was that libxml2 appeared in my /usr/lib64
directory as libxml2.so.2, libxml2.so.2.6.26, and libxml2-2.6.26 so the
configuration file could not determine which one to use. By making a
symbolic link to the latest version libsml2.so.2.6.26 resolved the
problem. Both nokogiri and mechanize were successfully installed

Hi Alice

Could you please tell me WHICH config file you changed or how? I'm
porting a tiny app from Windows to Ubunto and nokogiri port is one of
the problems I've had so far.

Thnaks

The thread you've posted to is over a year and a half old! That's ancient.

You may get better responses if you described what your issue is, attaching
information about your Ubuntu version, libxml2 and libxslt versions, and the
contents of your mkmf.log file after the failed gem installation.
