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...

Answer 1

Try this:

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

sudo apt-get install libxslt-dev libxml2-dev is sufficient for Ruby 1.9.3. – Bremerhaven

The OP clearly stated his ruby version. Installing ruby packages when he is already using rvm is of no real help. – Letty

Thanks. For me helped also: sudo apt-get install zlib1g-dev – Bellbottoms

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

Yes , this ran like a champ. You run this if you already have RUBY installed . and it worked. – Cathey

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

gem install --verbose nokogiri was exactly what I needed. Error: "virtual memory exhausted: Cannot allocate memory" - sigh – Mediate

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

On 14.0.4, using RVM, you need:

sudo apt-get install -y libgmp-dev

This is the solution to the latest error Ubuntu 14.04.4 LTS Ruby 2.3.0 – Communist

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:
