Unable to install NOKOGIRI 1.6.1 on Ubuntu 13.10 system.

[Gerald Brown]

Hello,

I have been trying to install NOKOGIRI 1.6.1 on my Ubuntu 13.10 system for several weeks now.

Tonight I think I figured out what the problem is.  I'm running Ruby 2.1.1 and nokogiri has NOT been upgraded yet to that version of Ruby.

The following is the error messages that I keep getting: "libxslt is missing.  please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.
-----
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options." and then it lists a bunch of possible configuration options.

I have tried to install the missing libxslt file and get error messages saying: "E: Unable to locate package libxslt"

I have read some posts here that say they are able to install v 1.6.0 but when I tried to install that it could NOT be found.

Any ideas when NOKOGIRI will be upgraded to Ruby 2.1.1???

Thanks,

Gerald

I don't have an Ubuntu system running 13.10, but Nokogiri 1.6.1
installs fine with ruby 2.1.1p76 on my Mac (OS 10.9.2).

You need to resolve the problem(s) from the error log. Perhaps you
can gist the entire log and someone using Ubuntu can help...

Per your suggestion I ran it again and the following is what is in the error files:

In file mkmf.log the following errors were found:

"conftest.c: In function ‘t’:

In the file gem_make.out the following error was found:

Could the problem be that I'm using Ubuntu on a PC and not using a Mac???

Also on the nokogiri web site it says that it requires Ruby 1.8 or 1.9.  That part of the web site may be outdated as are other portions of it.

Many, many people have nokogiri running on Ubuntu. And I just
now installed nokogiri 1.6.1 on an Ubuntu 12.04.4 LTS system with
Rubinius 2.2.6 (Ruby 2.1.0) without a problem.

Maybe you could spin up a 12.04 system and try it there? I have
no experience with 13.10. At least that would add a datapoint...

Yes, that's definitely outdated.
