When I try to install nokogiri gem on ruby-1.8.7-p334 [ x86_64 ] on Mac OS X 10.6, I get the following error:

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

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Answer 1

Before installing nokogiri gem, you need to get libraries installed. Here are the steps to do it with homebrew

# the rest of this snippet assumes installation of libxml 2.7.7. YMMV.
brew install libxml2
brew link libxml2

# install libxslt from source
wget ftp://xmlsoft.org/libxml2/libxslt-1.1.26.tar.gz
tar -zxvf libxslt-1.1.26.tar.gz
cd libxslt-1.1.26
./configure --prefix=/usr/local/Cellar/libxslt/1.1.26 
            --with-libxml-prefix=/usr/local/Cellar/libxml2/2.7.7
make
sudo make install

gem install nokogiri -- --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26

拥有玉米

sudo port install libxml2 libxslt
sudo gem install nokogiri

Answer 2

I tries all kinds of solutions I can found, including: . use brew to install libxslt / libxml2 / libiconv . tries to gem install with various --with-configurations sadly, they all didn t work for me, until I uninstalled MacPort and all installed ports.

然后简单地安装了“Nokogiri”、“gem”和“rdoc”等装置。

I don t understand the very details of why, but according to my own experiences of using MacPort (resulted in multiple sets of ruby/rake/gem(s) installed) and articles comparing brew and port, I will not go back to port.
