An error occurred while installing nokogiri (1.5.2)

Question

When I try to run a ruby on rails project I got an error:

An error occurred while installing nokogiri (1.5.2), and bundle cannot continue.
Make sure that 'gem install nokogiri -v 1.5.2 succeed before building.

I'm working on Ubuntu 10.10

My co-worker uses on Windows/RVM and does not have this problem.

Edit:

Answer 1

From the output:

libiconv is missing.  please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

Install libiconv.

Answer 2

sudo gem install nokogiri

Answer 3

It should not be necessary to install any additonal package. You can use the libraries includes with BitNami (in /opt/bitnami/common). You just need to load the BitNami environment and specify the path to libxml2 files. While testing this I got similar issue but with libxml2, a similar solution can be applied for the iconv error that you are receiving.

$/opt/bitnami/rubyconsole

$sudo gem install nokogiri  -- --with-xml2-dir=/opt/bitnami/common --with-xml2-include=/opt/bitnami/common/include/libxml2

Building native extensions.  This could take a while...

The solution of installing the system packages and used them should also work.
