unable to install nokogiri in ubuntu 12.04

Question

I am trying to setup rails env on my new ubuntu machine. But I am facing trouble while install nokogiri gem.. I have installed libxslt and libxml2 libs thourgh rvm pkg command as well as using apt-get. I thought it is showing me libxslt is missing error.

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

EDIT

I am using rvm setup and ruby 1.9.3

Answer 1

Try this:

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

Answer 2

For Ruby 1.9.3 and 2.0, libxslt-dev and libxml2-dev are required.

sudo apt-get install libxslt-dev libxml2-dev

Answer 3

this is what worked for me:

1. install nokogiri's dependencies

   sudo apt-get install libxslt-dev libxml2-dev

2. make sure nokogiri uses the system libraries

   export NOKOGIRI_USE_SYSTEM_LIBRARIES=1

3. install nokogiri with the --verbose option, to get a better understanding of any problems

   gem install --verbose nokogiri

Answer 4

Since I stumbled upon this, here's what I did to resolve:

sudo apt-get install ruby1.9.1-dev

Answer 5

On 14.0.4, using RVM, you need:

sudo apt-get install -y libgmp-dev

Answer 6

Install ruby via rvm and then install below libs:

sudo apt-get install libxslt-dev libxml2-dev

now try to install gem without sudo:

gem install nokogiri

Answer 7

apt-get install libxslt-dev libxml2-dev -y && export NOKOGIRI_USE_SYSTEM_LIBRARIES=1 && gem install --verbose nokogiri

Answer 8

for Centos / Redhat, try this: sudo yum install libxslt-devel libxml2-devel
