When trying to install nokogiri, I get:

Update:
Re-installing my compiler lets me install nokogiri, but I can't start rails server:

Last time I had this issue, the fix was to just re-install apple-gcc42, but that that doesn't seem to be the issue right now. Any ideas?

Answer 1

Looks like this issue has been already addressed: nokogiri will not install - ERROR: Failed to build gem native extension
Try
sudo apt-get install libxslt-dev libxml2-dev

Answer 2

You need libxslt and libxml2 to build nokogiri. And since you're on MacOS X, you need to install via MacPorts or Homebrew. For Homebrew, try:
brew install libxslt libxml2

Answer 3

homebrew 0.9
Apparently some people have had problems getting libiconv to install under homebrew 0.9 (see issue #442). Here’s what reportedly works:
brew install libxml2 libxslt
brew link libxml2 libxslt
Then install libiconv from source:
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
tar xvfz libiconv-1.13.1.tar.gz
cd libiconv-1.13.1
./configure --prefix=/usr/local/Cellar/libiconv/1.13.1
make
sudo make install
Then (finally) install nokogiri:
gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.7.8/include/libxml2 \
--with-xml2-lib=/usr/local/Cellar/libxml2/2.7.8/lib \
--with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26 \
--with-iconv-include=/usr/local/Cellar/libiconv/1.13.1/include \
--with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib

Answer 4

This workaround worked for me: https://github.com/opscode-cookbooks/xml/issues/19
1) Add liblzma-dev and z-lib1g-dev
sudo apt-get install liblzma-dev zlib1g-dev
2) Install using those
sudo /opt/chef/embedded/bin/gem install nokogiri -q --no-rdoc --no-ri -v "1.6.5" -- --use-system-libraries --with-xml2-include=/usr/include/libxml2

Answer 5

Following this worked for me http://jasdeep.ca/2013/10/installing-nokogiri-fails-os-x-mavericks/
It was a Mavericks issue involving developer tools.

Answer 6

A more comprehensive cases are detailed on nokogiri website
For me, on MacOs, it worked like as it is sugested here:
brew install libxml2
# If installing directly
gem install nokogiri -- --use-system-libraries \
--with-xml2-include=$(brew --prefix libxml2)/include/libxml2
# If using Bundle
bundle config build.nokogiri --use-system-libraries \
--with-xml2-include=$(brew --prefix libxml2)/include/libxml2
bundle install
When working with this, be certain to use $(brew --prefix libxml2)
because it will use the correct location for your Homebrew install.
