nokogiri - ERROR: Failed to build gem native extension

Question

I updated to the developer release of Lion and noticed I couldn't start rails apps anymore. Whenever I try to sudo bundle install, I get the following error:

Installing nokogiri (1.4.4) with native extensions /Library/Ruby/Site/1.8/rubygems/installer.rb:551:in `build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

Do you have Xcode installed? Do you have libxml2 and libxslt installed? These libraries are required by nokogiri. — Luis Lavena, Jul 19 '11 at 20:24

Try to install "libxslt1-dev" and "libxml2-dev" packages.

Thanks all - As i updated to Lion, I needed to install x code 4.1 to get the correct files behind the scenes for the bundler to install all of the correct bundles. All working sweet now!

Thanks for the tip, ran into a similar issue with a VIM plugin. – Peter Brown Jul 22 '11 at 21:58
Keep in mind that unlike other apps you download from the Mac App Store you have to manually install XCode using the 'Install Xcode' application. – Marc Jul 25 '11 at 01:16

I found this worked via https://github.com/sparklemotion/nokogiri/issues/1166#issuecomment-56545974.

$ brew install libxml2
$ gem install nokogiri -- --use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib/

Here's a more detailed approach if even this doesn't work. http://www.bullrico.com/2012/07/12/installing-nokogiri-after-updating-homebrew

Install the ruby1.8-dev gem (or rather, the applicable *-dev gem), which will include all the header files. See: This question

Consider installing a pre-1.6 version of nokigiri (gem install nokogiri -v '1.5.9')

Thanks! This solved my nokogiri intall issue on OSX 10.9.1 with XCode 5.0.2, Ruby 2.0.0 (nokogiri is a dependency for jekyll-import) – nicksuch Jan 15 '14 at 23:34

It says: "can't find header files for ruby". In other words, you're missing the ruby headers in order to compile libxml/nokogiri as a ruby extension.

Consider installing ruby 1.9 (or 1.8) using macports or rvm. I'm not 100% on the second, but the first will automatically make the relevant headers available.

I had similar problem, and after installing XCode 4.1, I also had to do the following command:

sudo port upgrade libxml2 libxslt

After that Nokogiri built without problems.

I tried a number of different solutions, but what finally worked for me was simply using a different version of 1.9.2.

I was having the same problem with 1.9.2-p280, but when I switched to 1.9.2-p180, I was able to install with out problems. Can't tell you why this worked, but it did.

I am running Lion and RVM (1.8.6).

Just had this problem again on an entirely different Lion system. Once again, the p180 worked, while the p280 did not. – Emerson Oct 28 '11 at 01:03
