I am working with Rails 3.2.1 and ruby 1.8.7 on Linux OS. I am trying to install Nokogiri for Authorize-net gem on a WHM Server. I am getting the following error :

gem install nokogiri -v '1.5.0'

Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:

The mkmf.log file states that libxslt is missing.

When trying to install libxslt-ruby, I'm getting the following error :

I am developing on Windows machine but the client's server is Linux. I tried googling but no luck.

Any help would be highly appreciated!

Thanks in advance!

I think "libxslt is missing" doesn't mean you have to install gem libxslt-ruby. It's telling you to install package libxslt-dev.

Just follow http://nokogiri.org/tutorials/installing_nokogiri.html and run:

sudo apt-get install libxslt-dev libxml2-dev
sudo gem install nokogiri

  • I've tried the above code but it says : `sudo apt-get install libxslt-dev libxml2-dev -bash: sudo: command not found` . – user3445812 May 07 '14 at 08:10
  • @user3445812 Do you get root access then? – Jun Zhou May 07 '14 at 22:14
  • The cpanel of WHM Server shows this notice : "Warning! You are logged in with the reseller or root password." But Still I get "sudo not found" message. – user3445812 May 09 '14 at 04:51
  • @user3445812 You are logged in as root. So you didn't need sudo. However, logging in as root isn't a good idea. – Jun Zhou May 09 '14 at 07:32
  • The linked page (at time of writing) does not suggest running 'gem install' with sudo. I wouldn't recommend it either. – mwfearnley Oct 28 '16 at 11:25
