Error installing Nokogiri 1.5.0 with rails 3.1.0 and ubuntu

Here is the error running bundle install vendor/gems on server:

Installing nokogiri (1.5.0) with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occured while installing nokogiri (1.5.0), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.5.0'` succeeds before bundling.

You can skip this part. The error message is pretty much self explanatory, but the website requires a few more words explaining the code.

Any thoughts?


You need to have all the necessary libraries installed on your machine. When you installed RVM , it should have listed this for you. On the current version of rvm, you can run rvm requirements to see the exact list. Right now, that list is:

sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion

You are missing some packages. Try running this (Linux only):

$ sudo apt-get install libxslt-dev libxml2-dev

It looks like a gem dependency error.

You need to run the bundle update command. It will resolve dependencies:

bundle update

You need to install libxml2.

On Mac OS, using homebrew, this will be:

brew install libxml2


Just do this:

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

then type this in terminal (linux) / cmd(windows):


Try this one if others doesn't work, its really work on me. Devtools for CentOS

When I used this code I got another error:

ERROR:  Error installing disposable:
    invalid gem: package is corrupt, exception while verifying: undefined method `size' for nil:NilClass (NoMethodError) in /home/admin/.rvm/gems/ruby-2.1.3@lol/cache/nokogiri-

I tried many different solutions, but helped med:

$ rm /home/admin/.rvm/gems/ruby-2.1.3@lol/cache/nokogiri-
$ gem update
$ gem install nokogiri

Other commands that can help:

sudo apt-get install synaptic
sudo apt-get update
sudo apt-get install qt4-dev-tools libqt4-dev libqt4-core libqt4-gui
sudo apt-get install build-essential
sudo apt-get install "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev
